R/colDetails.R

In vlulla/vlutils: Common utilities that I find useful

colDetails <-
function(DF) {
  classes <- function(x) {paste(class(x), collapse=", ")}
  columnnames <- colnames(DF)
  columnclasses <- sapply(DF, classes)
  columnidx <- seq_along(DF)

  data.frame(ColumnName=columnnames, ColumnClass=columnclasses, ColumnIndex=columnidx)
}
