A problem when using "TransCommuProfile()"

[ADSGF203com]

When I use the function TransCommuProfile() and it goes to step 6
"step6: score ligand-receptor relation (weighted, max, or mean) ####"
and I got this :
Error in FUN(X[[i]], ...) :
only defined on a data frame with all numeric variables
In addition: There were 50 or more warnings (use warnings() to see the first 50)

warnings()
Warning messages:
1: In cor(x, y, use = use, method = method) : the standard deviation is zero
2: In cor(x, y, use = use, method = method) : the standard deviation is zero
3: In cor(x, y, use = use, method = method) : the standard deviation is zero
4: In cor(x, y, use = use, method = method) : the standard deviation is zero

I just fix it with change the parameter ： method = “mean”
