Visualizing node label is easy using\n\ngeom_text2(aes(subset = !isTip, label=label))\n.\n\n\nIf you want to only display a subset of \nbootstrap\n (e.g. bootstrap \n\n80), you can't simply using\n\ngeom_text2(subset= (label \n 80), label=label)\n since \nlabel\n is a\ncharacter vector, which contains node label (bootstrap value) and tip\nlabel (taxa name). If we use\n\ngeom_text2(subset=(as.numeric(label) \n 80), label=label)\n, it will also\nfail since \nNAs\n were introduced by coercion. We need to convert \nNAs\n\nto logical \nFALSE\n, this can be done by the following code:\n\n\nnwk \n- system.file(\nextdata/RAxML\n,\nRAxML_bipartitions.H3\n, package='ggtree')\ntr \n- read.tree(nwk)\nggtree(tr) + geom_text2(aes(label=label, subset = !is.na(as.numeric(label)) \n as.numeric(label) \n 80))\n\n\n\n\nAnother solution is converting the bootstrap value outside \nggtree\n as I\nrecommended in \ngoogle\ngroup\n.\n\n\nq \n- ggtree(tr)\nd \n- q$data\nd \n- d[!d$isTip,]\nd$label \n- as.numeric(d$label)\nd \n- d[d$label \n 80,]\n\nq + geom_text(data=d, aes(label=label))\n\n\n\n\n \naesthetic\n mapping\n\n\n inherit \naes\n\n\nggtree(rtree(30)) + geom_point()\n\n\n\n\nFor example, we can add symbolic points to nodes with \ngeom_point()\n\ndirectly. The magic here is we don't need to map \nx\n and \ny\n position of\nthe points by providing \naes(x, y)\n to \ngeom_point()\n since it was\nalready mapped by \nggtree\n function and it serves as a global mapping\nfor all layers.\n\n\nBut what if we provide a \ndataset\n in a layer and the \ndataset\n doesn't\ncontain column of \nx\n and/or \ny\n, the layer function also try to map \nx\n\nand \ny\n and also others if you map them in \nggtree\n function. As these\nvariable is not available in your \ndataset\n, you will get the following\nerror:\n\n\nError in eval(expr, envir, enclos) : object 'x' not found\n\n\n\nThis can be fixed by using parameter \ninherit.aes=FALSE\n which will\ndisable inheriting mapping from \nggtree\n function.\n\n\n use \n$\n in aes\n\n\nNEVER DO THIS.\n\n\nsee the explaination in the \nggplot2 book\n2ed\n:\n\n\n\n\nNever refer to a variable with \n$\n (e.g., \ndiamonds$carat\n) in\n\naes()\n. This breaks containment, so that the plot no longer contains\neverything it needs, and causes problems if ggplot2 changes the order\nof the rows, as it does when facetting.\n\n\n\n\nsee also\n\n1\n\nand \n2\n.\n\n\n Annotation\n\n\n colouring edges by user data\n\n\nsee my blog post: \nEdge coloring with user\ndata\n\nand also my answer on\n\nhttps://github.com/GuangchuangYu/ggtree/issues/76\n and\n\nhttps://groups.google.com/forum/#!topic/bioc-ggtree/4GgivKqVjB8\n.",

New functions will only commit to \ndevel\n\nbranch.\n\n\nSometimes I may write blog post to introduce new functions which is not\navailable in \nrelease\n branch, you need to install the \ndevel\n version\nof \nggtree\n in order to use these new functions.\n\n\nYou can download the \ndevel\n version of \nggtree\n from\n\nhttp://bioconductor.org/packages/devel/bioc/html/ggtree.html\n and\ninstall it, or install the github version of \nggtree\n.\n\n\nThis also applied to other of my packages, including \nGOSemSim\n, \nDOSE\n,\n\nclusterProfiler\n, \nReactomePA\n and \nChIPseeker\n. If you got the\n\ncould not find function\n error, upgrade your installation to latest\nrelease. If the error still exists after upgrading to latest release,\nyou need to install the devel version.\n\n\n Text \n Label\n\n\n Tip label truncated\n\n\nggplot2 can't auto adjust xlim based on added text.\n\n\nlibrary(ggtree)\n## example tree from https://support.bioconductor.org/p/72398/\ntree\n-read.tree(text=\n(Organism1.006G249400.1:0.03977,(Organism2.022118m:0.01337,(Organism3.J34265.1:0.00284,Organism4.G02633.1:0.00468)0.51:0.0104):0.02469);\n)\nggtree(tree) + geom_tiplab()\n\n\n\n\nThis is because the units are in two different spaces (data and pixel).\nUsers can use xlim to allocate more space for tip label.\n\n\nggtree(tree) + geom_tiplab() + xlim(0, 0.06)\n\n\n\n\n Modify (tip) labels\n\n\nThis could be easily done via the \n%\n+%\n operator to attach the modified\nversion of the labels and than use \ngeom_tiplab\n to display the modified\nversion.\n\n\nraxml_file \n- system.file(\"extdata/RAxML\", \"RAxML_bipartitionsBranchLabels.H3\", package=\"ggtree\")\nraxml \n- read.raxml(raxml_file)\n\nlb = get.tree(raxml)$tip.label\nd = data.frame(label=lb, label2 = paste(\"AA\", substring(lb, 1, 5)))\nggtree(raxml) %\n+% d + geom_tiplab(aes(label=label2))\n\n\n\nsee also\n\n1\n\nand \n2\n.\n\n\n Formatting (tip) labels\n\n\nIf you want to format labels, you need to set \nparse=TRUE\n in\n\ngeom_text\n/\ngeom_tiplab\n and the \nlabel\n should be string that can be\nparsed into expression and displayed as described in \n?plotmath\n.\n\n\nFor example, the tiplabels contains two parts, species name and\naccession number and we want to display species name in \nitalic\n, we can\nuse command like this:\n\n\nggtree(rtree(30)) + geom_tiplab(aes(subset=node==35), label='paste(italic(\"species name\"), \"accession number\")', parse=T)\n\n\n\nAnother example for formating all tip labels:\n\n\nggtree(rtree(30)) + geom_tiplab(aes(label=paste0('bold(', label, ')~italic(', node, ')')), parse=TRUE)\n\n\n\nsee also\n\nhttps://groups.google.com/forum/?utm_medium=email\nutm_source=footer#!msg/bioc-ggtree/BA7g-npY1BM\n.\n\n\n Avoid overlapping text labels\n\n\nUser can use \nggrepel\n\npackage to repel overlapping text labels.\n\n\nFor example:\n\n\nlibrary(ggrepel)\nlibrary(ggtree)\nraxml_file \n- system.file(\nextdata/RAxML\n, \nRAxML_bipartitionsBranchLabels.H3\n, package=\nggtree\n)\nraxml \n- read.raxml(raxml_file)\nggtree(raxml) + geom_label_repel(aes(label=bootstrap, fill=bootstrap))\n\n\n\n\nFor details, please refer to \nggrepel usage\nexamples\n.\n\n\n bootstrap values from newick format\n\n\nIt's quite command to store \nbootstrap\n value as node label in \nnewick\n\nformat. Visualizing node label is easy using\n\ngeom_text2(aes(subset = !isTip, label=label))\n.\n\n\nIf you want to only display a subset of \nbootstrap\n (e.g. bootstrap \n\n80), you can't simply using\n\ngeom_text2(subset= (label \n 80), label=label)\n since \nlabel\n is a\ncharacter vector, which contains node label (bootstrap value) and tip\nlabel (taxa name). If we use\n\ngeom_text2(subset=(as.numeric(label) \n 80), label=label)\n, it will also\nfail since \nNAs\n were introduced by coercion. We need to convert \nNAs\n\nto logical \nFALSE\n, this can be done by the following code:\n\n\nnwk \n- system.file(\nextdata/RAxML\n,\nRAxML_bipartitions.H3\n, package='ggtree')\ntr \n- read.tree(nwk)\nggtree(tr) + geom_text2(aes(label=label, subset = !is.na(as.numeric(label)) \n as.numeric(label) \n 80))\n\n\n\n\nAnother solution is converting the bootstrap value outside \nggtree\n as I\nrecommended in \ngoogle\ngroup\n.\n\n\nq \n- ggtree(tr)\nd \n- q$data\nd \n- d[!d$isTip,]\nd$label \n- as.numeric(d$label)\nd \n- d[d$label \n 80,]\n\nq + geom_text(data=d, aes(label=label))\n\n\n\n\n \naesthetic\n mapping\n\n\n inherit \naes\n\n\nggtree(rtree(30)) + geom_point()\n\n\n\n\nFor example, we can add symbolic points to nodes with \ngeom_point()\n\ndirectly. The magic here is we don't need to map \nx\n and \ny\n position of\nthe points by providing \naes(x, y)\n to \ngeom_point()\n since it was\nalready mapped by \nggtree\n function and it serves as a global mapping\nfor all layers.\n\n\nBut what if we provide a \ndataset\n in a layer and the \ndataset\n doesn't\ncontain column of \nx\n and/or \ny\n, the layer function also try to map \nx\n\nand \ny\n and also others if you map them in \nggtree\n function. As these\nvariable is not available in your \ndataset\n, you will get the following\nerror:\n\n\nError in eval(expr, envir, enclos) : object 'x' not found\n\n\n\nThis can be fixed by using parameter \ninherit.aes=FALSE\n which will\ndisable inheriting mapping from \nggtree\n function.\n\n\n use \n$\n in aes\n\n\nNEVER DO THIS.\n\n\nsee the explaination in the \nggplot2 book\n2ed\n:\n\n\n\n\nNever refer to a variable with \n$\n (e.g., \ndiamonds$carat\n) in\n\naes()\n. This breaks containment, so that the plot no longer contains\neverything it needs, and causes problems if ggplot2 changes the order\nof the rows, as it does when facetting.\n\n\n\n\nsee also\n\n1\n\nand \n2\n.\n\n\n Annotation\n\n\n colouring edges by user data\n\n\nsee my blog post: \nEdge coloring with user\ndata\n\nand also my answer on\n\nhttps://github.com/GuangchuangYu/ggtree/issues/76\n and\n\nhttps://groups.google.com/forum/#!topic/bioc-ggtree/4GgivKqVjB8\n.",
