> The names method fails to check for validity of the assignment values. This can be fixed by calling colnames within names. See example below.
> {code}
> df <- suppressWarnings(createDataFrame(iris))
> # this is error
> colnames(df) <- NULL
> # this should report error
> names(df) <- NULL
> {code}
