Re: [R] removing missing values from a matrix

Thanks! It worked! There is another problem I want to subset the matrix 'red' in following manner: dim(red) 23688 164 a=red[1:23688,1:4] b=red[1:23688,5:8] c=red[1:23688,9:12] .. .. z=red[1:23688,161:164] If there any efficient way to do

Re: [R] removing missing values from a matrix

Here is one way to do it. BTW 'a'-'z' won't work because there are 41 splits. Use a list instead: red - matrix(seq(23688 * 164), nrow=23688, ncol=164) # create indices indx - split(1:164, cut(1:164, 41)) # now split matrix newMatrix - lapply(indx, function(x) red[, x]) str(newMatrix)

[R] removing missing values from a matrix

Hi! All, I am working with a large matrix of dimension 23689 x 162. Some of the values of this matrix is missing (NA). And it looks something like that: dim(red) 23689 162 red [,1] [,2] [,3] [,4] [,5] [1,]2 NA4 9 6 [2,]5 NA6 NA 1 [3,] NA
