Standardization of R data

Asked 1 months ago, Updated 1 months ago, 2 views

Hello
I would like to standardize the csv data read by R, but I get the error Error in colMeans(x,na.rm=TRUE): 'x' must be numeric'.When I checked with sapply(d, mode) (d contains the data read.table), it says all the data is numeric and I don't know why this error occurs.
Could you tell me the solution?

Try using class() or is.numeric() instead of mode() as you can see in the comment link

If d contains characters in the first frame (row1, column1) of the data read.table, why don't you leave it blank?
