Expand grid of data frames Details. expand.grid(. So does anyone know a good solution? The expand.grid () function is very handy for making complete grids. A data frame containing one row for each combination of the supplied The grid exports only data-bound columns. The posted answers address the OP's more specific question, so in case anyone is looking for a more general solution for data frames, here's a slightly more general approach: You can also just do a simple merge by NULL (which will cause merge to do simple combinatorial data replication): There is now also the crossing() function in package tidyr which can be used instead of merge, is somewhat faster, and returns a tbl_df / tibble. Use the R function expand.grid() to make a data frame with each possible combination of 3 possible values for each of the 3 parameters. Combining and Modifying Data Frames in R.
