'format.pval' has a major limitation in its implementation for example suppose a person had a vector like 'a' and the error being ?0.001. > a <- c(0.1, 0.3, 0.4, 0.5, 0.3, 0.0001) > format.pval(a, eps=0.001) The person wants to have the 'format.pval' output with 2 digits always showing like this [1] "0.10" "0.30" "0.40" "0.50" "0.30" "<0.001" How ever format.pval can only display this [1] "0.1" "0.3" "0.4" "0.5" "0.3" "<0.001" If this was the 'format' function this could be corrected by setting the 'nsmall' argument to 2. But 'format.pval' has no ability to pass arguments to format. I think that the best solution would be to give 'format.pval' a '...' argument that would get passed to all the 'format' function calls in 'format.pval'. I have attached a patch that does this. This patch is against svn r-release-branch and will also apply to r-devel.
