Hello list, Thanks in advance for any help.
I have many (approx 20) files that I have merged. For example d1<-read.csv("AlleleReport.csv") d2<-read.csv("AlleleReport.csv") m1 <- merge(d1, d2, by = c("IND", intersect(colnames(d1), colnames(d2))), all = TRUE) m2 <- merge(m1, d3, by = c("IND", intersect(colnames(m1), colnames(d3))), all = TRUE) [[alternative HTML version deleted]] ______________________________________________ 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.
