This error message suggests that you are trying to subset a matrix or data frame using column names, but the column names are not properly defined.
Here are a few possible solutions:
1. Check that the input object, x, is a matrix or data frame. If it is not, convert it to one using as.matrix() or as.data.frame().
2. Check that the column names you are using ("V6", "V11", "V22") match exactly with the column names in the input object. If they do not, try using the correct column names or using column indices instead.
3. If the input object does not have column names, you can add them using colnames(). For example, if your input object has 3 columns, you can add column names by running colnames(x) <- c("V1", "V2", "V3").
