Hi
I am trying to calculate the row sums of a matrix i have created
The matrix ( FeaturePresenceMatrix) has been created by
1) Read csv
2) Removing unnecesarry data using [-1:4,] command
3) replacing all the NA values with as.numeric(0) and all others with as.numeric
(1)
When I carry out the command
TotalFeature <- rowrowSums(FeaturePresenceMatrix, na.rm = TRUE)
I get the following error.
Error in rowSums(FeaturePresenceMatrix, na.rm = TRUE) :
'x' must be numeric
Any tips onhow I can get round this?
Yes, follow the posting guide and give the list a reproducible
example. We don't know a critical piece of information,
the class of your data. We know it's *not* numeric though,
which is what it needs to be. Use ?class, ?str, and
possibly give us a small sample with ?dput. That way, we can
reproduce the error.
