## Installation
### System setup
If you are the first time to install R, please don't install 32 bit R. Make sure to uncheck the '32-bit Files' box when you see the following window:
#### Window's user
For window's users, please install [rtools](https://cran.r-project.org/bin/windows/Rtools/history.html) based on your R version. Make sure to click 'Edit the system PATH' box when you see this window:
After installing rtools, install 'devtools' package with the following command. If it asks whether install the package that requires compilation, type 'y'.
```
install.packages('devtools')
```
#### macOS user
For macbook's users, please install gfortran with brew. If you have not installed brew, please check [this link](https://brew.sh/) to set up brew on your machine.
```
brew install gcc
```
After that, install 'devtools' package with the following command.
```
install.packages('devtools')
```
### Release Version
You can download the release version of the Single Cell Toolkit in
[Bioconductor v3.10](https://bioconductor.org/packages/release/bioc/html/singleCellTK.html):
```r
if (!requireNamespace("BiocManager", quietly=TRUE))
install.packages("BiocManager")
BiocManager::install("singleCellTK")
```
### Devel Version
You can download the development version of the Single Cell Toolkit in
[Bioconductor v3.11](https://bioconductor.org/packages/devel/bioc/html/singleCellTK.html)
or from this repository:
```r
# install.packages("devtools")
devtools::install_github("compbiomed/singleCellTK")
```
### R 3.4 Version
If you are still running an earlier version of R than 3.5, you can install
the following version from this repository:
```r
# install.packages("devtools")
devtools::install_github("compbiomed/singleCellTK", ref="r_3_4")
```
#### Troubleshooting Installation
For the majority of users, the commands above will install the latest version
of the singleCellTK without any errors. Rarely, you may encounter an error due
to previously installed versions of some packages that are required for the
singleCellTK. If you encounter an error during installation, use the commands
below to check the version of Bioconductor that is installed:
```r
if (!requireNamespace("BiocManager", quietly=TRUE))
install.packages("BiocManager")
BiocManager::version()
```
If the version number is not 3.6 or higher, you must upgrade Bioconductor to
install the toolkit:
```r
BiocManager::install()
```
After you install Bioconductor 3.6 or higher, you should be able to install the
toolkit using `devtools::install_github("compbiomed/singleCellTK")`. If you
still encounter an error, ensure your Bioconductor packages are up to date by
running the following command.
```r
BiocManager::valid()
```
If the command above does not return `TRUE`, run the following command to
update your R packages:
```r
BiocManager::install()
```
Then, try to install the toolkit again:
```r
devtools::install_github("compbiomed/singleCellTK")
```
If you still encounter an error, please [contact us](mailto:dfj@bu.edu) and
we'd be happy to help.
