# Many times we need to delete number of columsn in a data frame, in feature engineering process.
# Deleting the same with column numbers is possible, but is not a good idea from a maintenance standpoint.
# Using column names is a safer option.
# Use below code.
removeCols <- c("colA", "colB")
data.frame <- data.frame[, -which(names(data.frame) %in% removeCols]
