The itol.toolkit is an R package that provides helper functions for the Interactive Tree Of Life (iTOL). This package has been selected as a third-party tool in iTOL documentation and is recommended as one of the Top 40 New CRAN packages in January 2023 by the R Views channel of RStudio.

Support all 114 themes among all 23 template types in iTOL v6
High throughput generate templates in one command
Learn published template themes and use theme

Based on the dependence packages from CRAN and Bioconductor source. We recommend to use pak to install itol.toolkit package automatically to avoid problems.
install.packages("pak")
# from CRAN
pak::pak('itol.toolkit')
# from GitHub
pak::pak('TongZhou2017/itol.toolkit')pak method, you can still use the traditional installation method.

To install the stable versions, you can use the CRAN official repository. For development versions, you can use the GitHub repository. However, if you need to install packages from Bioconductor, you’ll need to use the BiocManager package.
If you encounter any issues during the installation process, such as problems caused by other systems, R versions, or dependency packages, please refer to the supplementary materials for a solution.
# load package
library(itol.toolkit)
# read data
tree <- system.file("extdata",
"tree_of_itol_templates.tree",
package = "itol.toolkit")
data("template_groups")
df_group <- data.frame(id = unique(template_groups$group),
data = unique(template_groups$group))
# create hub
hub <- create_hub(tree = tree)
## create unit
unit <- create_unit(data = df_group,
key = "Quickstart",
type = "DATASET_COLORSTRIP",
tree = tree)
## add unit into hub
hub <- hub + unit
## write template file
write_hub(hub,getwd())We have documents for every single function and some important tips for users. We also provided a ChatBot to help users learn the package interactively on Chat Thing.
