Switching between horizontal and vertical GSEA plots leads to different P-value results.

Here are examples of GSEA plots for the same gene set but with different layouts:

The p-values and NES do not match between different layouts of the plot. I believe that this issue may be resolved by setting a seed before running fgsea:

Line 78 in c20ab5e

fgseaRes <- fgseaMultilevel(list(p=pathway), ranks, sampleSize = 101, nproc=1, eps = eps/2)
