Hi Elham, Your image didn't get through, maybe PNG will work. Label crowding is a common problem, whether horizontal or vertical. One solution is to set a maximum length on label text (see truncString in the prettyR package). Others are to stagger labels (staxlab in plotrix) or shift them apart when crowded (spread.labels in plotrix). These functions may not work with heatmap.2 (gplots). It will be easier to suggest something if you can get your image through.
