Hello,
I am relatively new to R. I am trying to do the following
and cannot figure out a relatively fast, clean method of doing it in R.
Here is a simple sample of what my data set looks like:
ID Try Num Dir
1 1 1 1
1 1 2 4
1 1 3 2
1 2 1 4
1 2 2 3
2 1 1 3
2 1 2 1
2 2 1 1
2 2 2 2
2 2 1 4
2 3 2 1
2 3 1 3
3 1 1 1
3 1 2 4
3 1 3 1
3 1 4 3
3 2 1 4
3 2 2 3
I would like to calculate the percent
occurrence of each possible value of Dir (in this case, there are four:
1, 2, 3 and 4) for each ID and Num. E.g., so the output would be a table
with each row as a different value of ID (in this case, 1, 2 and 3),
and there would be a separate column for each instance of Dir for each
instance of Num (in this case, for each of the 4 values of Num, there
would be 4 columns for Dir). In this case, the first entry of this table
would be .5, since for ID 1, when Num=1, Dir=1 in one out of two cases.
Any help would be greatly appreciated!
Thank you.
