Hi Alan, The sample names (columns) and KEGG pathway names (rows) are actually not clipped, except that they extend beyond the visible area. You may open your PDF file in Adobe Illustrator, and you can see and edit the heatmaps for better effects. The relevant function called here is gs.heatmap, which further calls heatmap2. Both of these functions are internal functions, and have been optimized for the common cases and are not intended to be changed. If you have really long sample names, you may try to make them shorter. If you really want to adjust the margins through these functions, you need to change the values of argument "margins" where heatmap2 is called within gs.heatmap. For details, type in gage:::gs.heatmap . I would suggest to make copies of these functions first then you make these changes on your own copies. HTH.
