hi ,R users I read a series of file by the command shown as below. cop_x_data<-read.table(flnm,skip=2) the first two line of the files are headfile and I skip them. and sometimes the original data file is null and there is no any data in the file except for the head information. At this situation,my command would be in the error and tell me that there is not data in the file and can not go on. How can I go on read the files even if the file is null?
There are many examples in the archives that show how to recover from errors using 'tr'y and 'tryCatch'.
