First time using R and have so many basic questions. The problem that I have confronted is combining rows. I have a data frame that contains daily rain falls from 60 to 80. There are 27 columns which are Year,month, day, and record in hours.
I am trying to combine the 4th column to the 27th to get daily rain fall data. rowSums() works in the case of merging all rows but in my case, I need to be selective. How should I start? -- View this message in context: http://r.789695.n4.nabble.com/combining-rows-tp3790068p3790068.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
