Re: [R] Question about subset

Please read the "Details" section of the help file -- it essentially tells you what to do by directly using indexing; e.g. for a vector, index by: [is.na(subset) | subset] . Adjust as necessary for your data structure.Or look at the code of, e.g. subset.data.frame and create your own subset versi

[R] Question about subset

Hi, The help page for subset states "subset: logical expression indicating elements or rows to keep: missing values are taken as false." Before I try to re-invent the wheel, I would like to know if one of the base or recommended packages would contain a variant of the subset function that would

Hello, I gather data from 5 objects and 5 data. frames and would like to join information. join: pb_SM + pb_T + pb_P + pb_F + pb_SJ = total_pb join: sdmdata_SM + sdmdata_T + sdmdata_P + sdmdata_F + sdmdata_SJ =total_sdmdata code: rbind, merge? total_pb<- ?? total_sdmdata<- ?? 1 absva

I do not provide consulting services, so you're on your own. As I said earlier, you need to follow the posting guide and show us what efforts you have made. "None" will probably not succeed in getting anyone to help. Nor should you expect anyone on this list to be familiar with Stata and/or to do y
