在data.frame中不包含0个元素的子集行

Question

I have a data.frame that looks like this:

  cln1 cln2 cln3 cln4 0 1 2 0 3 9 7 12 1 0 13 0 4 98 23 11 

I would like to subset only that rows and columns not containing 0 elements. The desired output will be:

  cln1 cln2 cln3 cln4 3 9 7 12 4 98 23 11 

Answer 1

Assuming your data.frame is called "mydf":

> mydf[!rowSums(mydf == 0), ]
  cln1 cln2 cln3 cln4
2    3    9    7   12
4    4   98   23   11
