Hi folks, I am struggling with something that should be simple. Here is my data frame: head(jData[,1:8]) x study_id qx_1_v4j qx_1a_v4j qx_1b_v4j qx_2_v4j qx_2a_v4j qx_3_v4j 1 1 MCJ1001 1 1 1 1 1 1 2 2 MCJ1002 1 1 2 1 2 0 3 3 MCJ1003 1 1 1 0 NA 1 4 4 MCJ1004 1 1 2 1 3 0 5 5 MCJ1005 1 1 1 1 1 1 6 6 MCJ1006 1 1 0 1 3 0 I want to run table() on each of the columns and compile the results into a single list/table/whatever works with the first column being the column name. The resulting output will have different numbers of columns per row. Is this possible? Regards, Sumit
