subset - R: Undefined Columns Selected Error when Subsetting DF -


i have dataframe data following structure:

classes ‘tbl_df’ , 'data.frame':  4391 obs. of  53 variables

when try subset top 100 rows using

data100 = data[1:100,]

i error:

error in `[.data.frame`(x[[i]], ...) : undefined columns selected

what reason?

found answer - needed use

as.data.frame(data)

before subsetting because tbl_df not subsettable same way data frame. needed due using dplyr earlier , outputting table instead of df.
