我正在尝试使用pheatmap()函数生成一个heatmap。但是，我看到一个错误，在dataframe中存在NA/NaN/Inf。我检查它，但是里面没有NA/NaN/Inf值。这个函数以前起过作用，所以我不知道我做错了什么.有什么建议吗？

这些错误和警告的可能原因之一是矩阵mat中存在一个非数字向量。
例如，iris数据帧中的前四列是数字向量，第五列是字符向量。如果将所有列作为pheatmap的输入，则会弹出错误和警告消息：
pheatmap(as.matrix(iris)) # failed.
#Error in hclust(d, method = method) :
# NA/NaN/Inf in foreign function call (arg 10)
#In addition: Warning messages:
#1: In dist(mat, method = distance) : NAs introduced by coercion
#2: In dist(mat, method = distance) : NAs introduced by coercion如果只包含数字列，则执行该函数时不存在错误或警告。
pheatmap(as.matrix(iris[,1:4])) # succeeded.页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
