Hi,
I have two matrix from two different .csv files.

#load .csv files
a <- as.matrix(read.table("Whirr_127.csv", header=T, sep=",", row.names=1))
b <- as.matrix(read.table("Files_Whirr_127.csv", header=T, sep=",",
row.names=1))
a
b

I managed to do transpose to 'b' without any error.

transpose_task <- t(b)
transpose_task

But, when I tried to do multiplication (a%*%transpose_task), an error
occured.

td <- (a%*%transpose_task)
td

Here is the error:
ERROR:  requires numeric/complex matrix/vector arguments
ERROR:  object 'td' not found

Anybody can help me to solve this?

Thank you
