Cannot plot simple series

[Fernando Saldanha]

This is my first day with RKWard and my third day with Linux
(Kubuntu), so please bear with me.

RKWard is running well and has dealt with quite complex code. I am
very excited about using it. However, it has not been able to plot
even the simplest charts. It also was not able to plot charts
generated by ggplot2, even though that code worked fine in RGui and
RStudio. Here is an example of a chart using base R:

> zz <- 1:100
> plot(zz)

Here is the error generated:

Error in RK() : Graphics API version mismatch
4: RK()
3: dev.hold()
2: plot.default(zz)
1: plot(zz)

Any help will be greatly appreciated,

Here is the output from running rk.sessionInfo():
