Hi dear R users. I got a file that I need to extract the third column (or word) of the last line of files that has a diffrent amounts of rows. It works with
x<-read.tables("file") x[1,3] This returns the proper result but as the files is large this takes time and uses memory that is just unneccery. p<-read.table(textConnection(system("tail -1 file",intern=TRUE))) p[1,3] This also returns the proper result but then requires the system to be unix based witch is quite silly if you ask me. Would rather just use R commands. So Im wondering if anyone of you got a better way of reading the last line of a file and extracting the third column (or word) of that line.
