问题，pheatmap和heatmap.2结果不一样

对同一组数据聚类时发现，pheatmap和heatmap.2结果不一样，差别很大？是什么原因呢？
pheatmap(data, cluster_cols=FALSE,clustering_distance_row="correlation",clustering_method = "complete",color=colorRampPalette(c("green","black","red"))(100), revC=FALSE, scale="row", margins=c(5,10),fontsize_row=8,cellheight=10,cellwidth=30)


heatmap.2(data, col=redgreen(100),scale="row",margin=c(5,20),key=TRUE,density.info="none",trace="none",cexRow=0.7)
