Hi

What I'm trying to do is probably right in front of me with tidyverse but I'm not that experienced in R. Here's my data:

GroupA, GroupB, x

1,1,53.1

1,1,49490

1,1,30129301

1,1,....

1,1,1973

1,2,4394829

1,2,313221

1,2,...

1,2,9090909

1,3...

1,15,967647634

...

4,1,...

4,15,...

5,1,...

5,5,877656

5,5,...

5,5,54321 (last row of data)

So in short we have 5 possible values for GroupA and 15 for Group B so each value of x can fit into one of 75 combinations of Group A and Group B.

For each combination of groups, what I want is not just the min, max, std, mean etc for each of the 75 combinations but a distribution (probably quantiles or every 5%) so I can do a frequency distribution - well 75 distributions to be precise. So for example, for each combination of GroupA and GroupB, I want R to calculate the 5th, 10th, ... 95th, 100th percentile value, then count the number of values of x for each percentile - to end up with a frequency distribution with 21 points (including 0).

I'd also like these automatically plotted (i.e. 75 charts) if possible - but not so worried about that.

What I'm really after is looking at whether any of these distributions show a long tail on either side of the mean. I've always hated box plots (and inter quartile ranges - too imprecise for me) so much prefer seeing the distribution - then I can worry about the umpteen ways of comparing distributions (coeff of skewness, kurtosis) etc.

Thanks
