初始数据类似如下:
填充下缺失值
data[data==0] <- NA
data[is.na(data)] <- min(data,na.rm = T)*0.01
pheatmap(log10(data))
pheatmap(data,scale = "row")
直接取log绘制不报错,但做
scale
时报错:
Error in hclust(d, method = method) :
NA/NaN/Inf in foreign function call (arg 11)
原因是数据中有标准差sd为0的行,做归一化时报错。pheatmap中做归一化采用的是scale方法:
因此如果要做scale,需要将这样的行去掉:
test <- data[apply(data, 1, function(x) sd(x)!=0),]
pheatmap(test,scale = "row")

eclipse报错:The method convert(String) of type DateConvertor must override a superclass method;
@Override must override a superclass method 问题解决 如果在使用Eclipse开发Java项目时,在使用 @Override 出现以下错误: The method *** of type *** must override a superclass method 主要是因为你的Compiler是jdk5,(5不支持@Override等形式的批
