prodplot and labels

[neuwirthe]

There is a problem with prodplot (from productplots)

with labels derived from variables with spaces in the variable name

library(productplots)
data(happy)
happy1 <- mutate(happy,`marital status` = marital)
prodplot(happy1, ~ health + marital)
prodplot(happy1,~ health + `marital status`)
prodplot(happy1,~ health + `marital status`,c("vspine","hspine"))
prodplot(happy1, ~ health + sex + marital,c("vspine","hspine","hspine"))
prodplot(happy1, ~ health + sex + `marital status`,c("vspine","hspine","hspine"))

All plots but the last one word, so in principle prodplot can deal with spaces in variable names.

The last plot produces an error

Error in `[.data.frame`(labels, x, col) : undefined columns selected

I suspect that producing the x-axis-label which concatenates two variable labels

has a problem.

I just noticed: even when prodplot prints the axis title containing spaces, it will not display the axis tick mark labels in that case.
