Hi @rbutleriii,
I am not sure if you found a solution for your problem, but I encountered the issue just now and it is an heatmap.2
issue if all values in the matrix are the same (e.g. if all padj.values are 1).
Reproducible example:
library("gplots")
plot.mat <- matrix(rep(1, 6), , nrow = 3, ncol = 2, dimnames = list(letters[1:3], letters[4:5]))
heatmap.2(plot.mat)
plot.mat <- matrix(rep(0.5, 6), , nrow = 3, ncol = 2, dimnames = list(letters[1:3], letters[4:5]))
heatmap.2(plot.mat)
# replace any number
plot.mat[1, 2] <- 0.01
heatmap.2(plot.mat)
I will try to add an error message for next release.
Thank you for reporting.
Hi, I have multiple sets of gene lists and am running pairwise enrichment using the following function on them:
Usually works fine, but on one comparison (5 sets x 6 sets), I get three enrichments with the standard Heatmap (0.031, 6e-03, 6e-03), but a cryptic error and a blank pdf for the multiple testing set:
Am I correct in thinking this means none of the enrichments remained after multiple correction? Could it return an error as such?
