Description

Usage

matchColumnName(data.frame.cols, reqCols, ignore.case = FALSE)

Arguments

data.frame.cols

column names of a data.frame. One can also provide a data.frame, which may however cause worse performance since the data.frame is copied

reqCols

required columns

ignore.case

logical, whether the case is considered

Value

A vector of integers as indices

Examples

# NOT RUN {
myTestDf <- data.frame(HBV=1:3, VFB=0:2, BVB=4:6, FCB=2:4)
myFavTeams <- c("HBV", "BVB")
matchColumnName(myTestDf, myFavTeams)
myFavTeamsCase <- c("hbv", "bVb")
matchColumnName(myTestDf, myFavTeamsCase, ignore.case=TRUE)
## NA will be returned in this case if ignore.case is set to FALSE
matchColumnName(myTestDf, myFavTeamsCase, ignore.case=FALSE)

# }
