R: Undefined Columns Selected Error when Subsetting DF

I have a dataframe data with the following structure:

Classes ‘tbl_df’ and 'data.frame':  4391 obs. of  53 variables

When I try to subset it to get the top 100 rows using

data100 = data[1:100,]

I get this error:

Error in `[.data.frame`(X[[i]], ...) : undefined columns selected

What could be the reason?

Found the answer - I needed to use

as.data.frame(data)

before subsetting because tbl_df is not subsettable the same way as a data frame. This was needed due to using dplyr earlier and it outputting a table instead of a df.
