Hi I have a table read from a mysql database which is of the kind clusterid clockrate
I obtained this table in R as clockrates_table <-sqlQuery(channel,"select...."); I have a function within which I wish to extract the clusterid for a given cluster. Although I know that there is just one row per clusterid in the data frame, I am using subset to extract the clockrate. clockrate = subset(clockrates_table, clusterid==15, select=c(clockrate)); Is there any way of extracting the clockrate without using subset. In the help section for subset, it mentioned to "see also: [,..." However I could find no mention for this entry when I searched as "?[", etc. The R manuals also, despite discussing complex libraries, techniques etc, dont always seem to provide such handy hints/tips and tricks for manipulating data, which is a first stumbling block for newbies like me. I would greatly appreciate if you could point me to such resources as well, for future reference. Thanks Lalitha ____________________________________________________________________________________ 8:00? 8:25? 8:40?
