[R] Duplicate row names are not allowed

[peter dalgaard]

Presumably, RCommander's readXL generates an invalid data frame (John?). To investigate, look at

row.names(Dataset)

and to fix 

row.names(Dataset) <- NULL

If the issue is that Dataset really isn't a data frame, maybe try Dataset <- as.data.frame(Dataset).

[Your screenshot made it through to here, but not the data. Notice, as a general matter, that it is preferable to give your code as part of the message text; it is hard to copy-paste from a .png]
