The tRNAdb and mttRNAdb ([Juehling et al. 2009](#Literature)) is a compilation of
tRNA sequences and tRNA genes. It is a follow up version of the database of
[Sprinzl et al. (2005)](#Literature).
Using `tRNAdbImport` the tRNAdb can be accessed as outlined on the website
[trna.bioinf.uni-leipzig.de](trna.bioinf.uni-leipzig.de) directly via R. The
results are returned as a `GRanges` object and can be further used in a
BioC context.
# Installation
The current version of the `tRNAdbImport` package is available from Bioconductor.
```{r}
if (!requireNamespace("BiocManager", quietly = TRUE))
install.packages("BiocManager")
BiocManager::install("tRNAdbImport")
# Load and attach the package
library("tRNAdbImport")
```
