plot with invalid 'type' argument yield misleading error message #2
When calling the 'plot' method with an invalid 'type' argument (e.g. with a typo), a misleading error message (see below) is shown. It would be an improvement to check the 'type' argument against the available options and return a useful error message, informing the user that this type is not existing.
data(StemCell)
w <- Venn(Sets=StemCell[1:2])
Weights(w) <- 1:4
plot(w, type="foo")
Error: length(cutedge) == 1 is not TRUE
In addition: Warning messages:
1: In .local(from, to, graph) :
The following edges already exist and will be replaced:
i2|i3
2: In .local(from, to, graph) :
The following edges already exist and will be replaced:
i3|i2
