[rkward-users] [Help] RE: Error Starting R- RKward

[quote]Will it be an issue if I run rkward and rcommander in the same
ubuntubox?[/quote]

No. Co-installing Rcmdr and rkward on one box has never been a problem to the
best of my knowledge.

There have been problems in the past with running Rcmdr inside an RKWard session.
And in fact, as I just found out, the problem came back with RKWard 0.5.5. I
have just fixed this in the development version, so with the next daily build,
you can even run [code]library(Rcmdr)[/code] inside an RKWard session.

[quote]I could not be able to generate the boxplot graph from the rkward-plot-boxplot
(instead I had to use the Rconsole in the rkward)[/quote]

This part of the problem is fixed, though, isn't it? I.e. you can create [b]some[/b]
boxplots?

[quote]There is no options to plot by a group variable (which in my case is
Treatment in M).[/quote]
[quote]Also, I was working on the scatter plot the other day and I could not
be able to put a regression line through the points.[/quote]

Yes, unfortunately, some of our features are still terribly rudimentary. You
will have to look into the underlying R code, or use other packages, in these
cases (or, in the case of the box plot: re-organize your data). And of course
help with improving our dialogs is always welcome.
See http://rkward.sourceforge.net/documents/devel/plugins/index.html for information
on how to do that.

[quote]Also is there a way to save the graphs as eps image from the output
(rkout.html does generate a very nice report, however the default graphics quality
is low)?[/quote]

You can change the file format and quality used for rkout.html in Settings->Configure
RKWard->Output. EPS is not a supported option, here, but SVG is. To get at EPS
images (and a variety of other formates), typically the fastest way is this:
In the plot dialog, check the "Preview" box. Once satisfied with the preview,
in the preview window, select Device->Export... from the menu.
