Re: [R] multiple uses ifelse function

Hi Letter, This should do it: testchange <- ifelse(testseq <= 4,'x', ifelse(testseq >= 5, 'y', testseq)) Read it as: if testseq <=4, print x, ifelse test seq >=5, print y, any other case, print testseq. [[alternative HTML version deleted]] __

[R] multiple uses ifelse function

Readers, Could someone please explain how to apply the function 'ifelse' to change a vector, for various conditions? testseq<-seq(1:20) testchange<-ifelse(testseq<=4,'x',testseq) testchange<-c(ifelse(testseq<=4,'x',testseq),ifelse(testseq>=5,'y',testseq)) The last instruction causes the
