Hi again,

Yes you are right I should have included an example of the file

It looks like this after reading in the data and using tapply I arrive at the following

> Alt5rimc_mean

             A B C D E F

1965  8.423645  0.208  1.6296296  0.0000000  0.0000000  0.0000000
1966 30.881773 27.344 13.2592593 26.2962963 22.3090909 22.4545455
1967 29.783251 15.824 24.3333333 26.3333333 19.5090909 34.4545455
1968 17.827586 31.776 14.7777778 23.8888889 25.2000000 21.7272727
1969 27.507389 30.520 12.2222222 30.8518519 25.8363636 13.7272727

1972 32.502463 19.736 34.6666667 39.8888889 28.5272727 43.6363636
...
2000 44.610837 11.208 1.7777778 15.6296296 17.8545455 7.5454545

I do not have example code, to share, but I was initially thinking that it should be approached with as follows:

for (i in 1 to 6)             #  index for columns
  for (j in 1 to 36)        # index for rows

barplot(data[i][j])

But that is very crude and of course it does not work. Hence the request for assistance.

Thanks

Yes you can automate it. The exact way would depend on how your data is structured and what you want the graphs to look like. It is hard to say without an example of the data and at least the command that your are using to create a single plot.
