How does one remove columns either by name ("Exp1", "Exp2", "Exp3", ...
"Exp100") or by column number from a matrix or data.frame using a list of
names mynames = ("Exp10,"Exp20","Exp55","Exp67")
I would something in the form of (I know this does not work):
myMatrixEdited = myMatrix[,-mynames]
Or I would like to find the column numbers of the names in the list, and use
the column numbers to remove the columns in the matrix or data.frame.
