## How to save row values from a matrix into one vector?

 Dear R users, I guess, I have a quit simple problem, but I'm not getting the solution. I create a matrix like this: test <- matrix(seq(1,3,1),ncol=5,nrow=3) then I want to create one vector, consisting of every row of the matrix. My first idea was to do this with a for loop. op <- vector() for (o in 1:3){ op[o] <- as.vector(test.id[o,]) } The results should be like this: [1] 1 1 1 1 1 2 2 2 2 2 2 3 3 3 3 3 thanks!

 This is want you want: op <- as.vector(t(test)) JC 2011/9/16 Chris82 <[hidden email]>: > Dear R users, > > I guess, I have a quit simple problem, but I'm not getting the solution. > > I create a matrix like this: > > test <- matrix(seq(1,3,1),ncol=5,nrow=3) > > then I want to create one vector, consisting of every row of the matrix. > My first idea was to do this with a for loop. > > > op <- vector() > > for (o in 1:3){ > op[o] <- as.vector(test.id[o,]) > } > > The results should be like this: > > [1] 1 1 1 1 1 2 2 2 2 2 2 3 3 3 3 3 > > > thanks! > > > -- > View this message in context: http://r.789695.n4.nabble.com/How-to-save-row-values-from-a-matrix-into-one-vector-tp3818415p3818415.html> Sent from the R help mailing list archive at Nabble.com. > > ______________________________________________ > [hidden email] 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. > ______________________________________________ [hidden email] mailing list https://stat.ethz.ch/mailman/listinfo/r-helpPLEASE do read the posting guide http://www.R-project.org/posting-guide.htmland provide commented, minimal, self-contained, reproducible code.
