Hi, when I was trying to run the above code, the following warnings are shown in the R console. Does anyone know how to get rid of it? I have tried suppressWarnings() , warning = FALSE on the chunk setting, and it is still there.
thx!!

To get rid of xgboost warnings you can set verbosity = 0 which will be passed on by caret::train to the xgboost call:
library(caret)
library(mlbench)
data(Sonar)
cv <- trainControl(
method = "cv",
number = 5,
classProbs = TRUE,
summaryFunction = prSummary,
seeds = set.seed(123))
turn_grid_xgb <- expand.grid(
eta = 0.1,
max_depth = 5,
min_child_weight = 1,
subsample = 0.8,
colsample_bytree = 0.8,
nrounds = c(1,5)*200,
gamma = 0)
set.seed(123)
xgb_1 <- train(Class~., data = Sonar,
method = "xgbTree",
tuneGrid = turn_grid_xgb,
trControl = cv,
verbose = FALSE,
metric = "F",
verbosity = 0)
