R的新手。我正在尝试从mlbench软件包的Glass $ Fe中将0.00值添加.01。

Question

I don't what to assign the 0.00 as NA but by simply adding .01 to all values that are 0.00. I need this to eliminate an error using symbox from the car package.

symbox(Glass$Fe, data=Glass, powers=c(3,2,1,0,-0.5,-1,-2)) Error in bc1(out, lambda) : First argument must be strictly positive.

My instructor recommended not to remove the 0.00 values just make them slightly positive.

Thanks,

Answer 1

一个更完整的问题将包括代码，以加载任何包含symbox程序包以及示例数据集，但是如果唯一的愿望是将Glass $ Fe .01的值移向正值，则尝试：

symbox(Glass$Fe+0.01, data=Glass, powers=c(3,2,1,0,-0.5,-1,-2))
