Dear all, How can I do the subset fucntion from the table?
What table?
I want to do the subset for the less than 50. I tried b8a<-subset(b8, (table(g$book)<50)==TRUE) but it didn't work.
And you neither shown us what these structures are nor posted an error message.
Thanks. table(g$ book )
The subset function is for dataframes. Tables are essentially matrices. Use logical indexing with "[".
119 121 134 160 161 170 175 179 190 193 225 226 256 260 130 89 50 87 74 23 85 47 93 64 16 69 48 38
The top row are names and the bottom row are values Perhaps (but how b8 enters into this remains unclear) : tbl <- table(g$ book ) tbl[ tbl < 50]
