Hello all, I am trying to automate a list to be filled in a FOR LOOP. Basically I need to load info from a third source and store it into a list. This list goes to object "A"; The next list brought in by the LOOP goe to object "B".. os on ans so forth.
When the iteration on the LOOP goes well (which means it isn't empty) I get something like this: A [[1]] [,1] [1,] "1130" [2,] "1132" [3,] "1134" [4,] "1136" [5,] "1138" [6,] "1140" [7,] "1142" [[2]] [,1] [1,] "7.54" [2,] "6.55" [3,] "4.20" [4,] "3.50" [5,] "2.92" [6,] "2.42" [7,] "1.99" However when the source is empty I get the following: A [[1]] [,1] [[2]] [,1] I need to store NA in the latter one. I have tried A[is.na(A)] but I get an error message. Any help would be greatly appreciated.
