在每一行中查找最小正值(不包括0) [英] Find Minimum positive value in each row (exclude 0)

问题描述

我目前正在处理矩阵，我想在每一行中找到最低的正值.

I am currently working with a matrix and I want to find the lowest positive value in each row.

使用apply(my.matrix，1，min)无效，因为输出始终为0 ...

Using apply(my.matrix,1,min) won't work since the output will always be 0...

是否可以找到除0以外的最低值?

Is there a way to find the lowest value excluding 0?

推荐答案

您可以使用匿名函数来做到这一点.

You can do this with an anonymous function.

apply(my.matrix, 1, FUN = function(x) {min(x[x > 0])})
