Windows users may need to run with administrator rights (either R or the command prompt, depending on the way you are installing this package). Rtools must be installed.
You can use a command prompt to install via command line:
cd R-package
R CMD INSTALL --build .
You can also install directly from R using the repository with devtools:
devtools::install_github("Microsoft/LightGBM", subdir = "R-package")To install LightGBM from a specific commit, you can specify the reference, such as the following to install the first release of the R package for LightGBM:
devtools::install_github("Microsoft/LightGBM", ref = "1b7643b", subdir = "R-package")You can check quickly if your LightGBM R package is working by running the following:
library(lightgbm)
data(agaricus.train, package='lightgbm')
train <- agaricus.train
dtrain <- lgb.Dataset(train$data, label=train$label)
params <- list(objective="regression", metric="l2")
model <- lgb.cv(params, dtrain, 10, nfold=5, min_data=1, learning_rate=1, early_stopping_rounds=10)- Please visit demo.
