I am very sorry for such a simple question, but I am struggling with "split". I have the following data frame: x<-data.frame(A=c(NA,NA,NA,NA,"split",NA,NA,NA,NA,"split",NA,NA,NA,NA,"split",NA,NA,NA,NA), B=c("Name1","text1","text2","text3",NA,"Name2","text1","text2","text3",NA,"Name3","text1","text2","text3",NA,"Name4","text1","text2","text3"), C=c(NA,1,NA,3,NA,NA,4,5,6,NA,NA,7,8,9,NA,NA,3,3,3),D=c(NA,1,1,2,NA,NA,5,6,NA,NA,NA,9,8,7,NA,NA,2,2,2), E=c(NA,3,2,1,NA,NA,6,5,4,NA,NA,7,7,8,NA,NA,1,NA,1)) print(x)
All I want to do is to split x, i.e., to create a list of data frames that are currently separated by the word "split" in column A. In this example, it would be 4 data frames, the first of them being: A B C D E NA Name1 NA NA NA NA text1 1 1 3 NA text 2 NA 1 2 NA text3 3 2 1 etc. I tried: split(x, x$A) split(x,x$A == 'split') split(x,!is.na(x$A)) But nothing produces what I need.
