indexing question
...stion, at least i believe so. The main reason i post it here, is that brackets and $ are hard to google. How do I index correctly, if i just want to display the whole dataset conditioned on the fact that some particular column equals one. I know i can do something like: data$somecolumn[data$particularcol ==1] . That will show all "some column" values where the particular column is 1. Unfortunately something like : data[data$particularcol ==1] does not work to get the whole matrix. is there some easy way except the % in % stuff ? Thx in advance
