It is a kind of question of uniformity and how close to R should be rkward. Let me explain. We probably should decide (probably as plugin policy) if we will use package like lattice and/or gplots that give different colors from the traditional R plot engine. For example if use barplot2 gives color barplots thus barplot gives gray plots. Lattice package gives more different colors. I hope you understand what I mean.
<br><br>One more thing is how far to get barplot. For example for barplot you can get stacked bars, juxtaposed, or vertically or horizontically bars. Should we give options for these and if yes in a different tabs? Or is it enough this I have done? Neither on stacked nor on vertically bars we can add values. I took a look to SPSS, Minitab and Rcmdr, and they use only vertically bars. What do you think?

<br>We have spoken about this issue in the past (I think). I suggested something<br>like a "First Run Wizard" which asks the user to check if there are plugins<br>which require non-locally stored packages and subsequently starts the
<br>(existing) procedure to install them. Actually there is no need for a wizard<br>but an option in settings would also be good in therms of useability. I'm<br>saying this because it can happen that people on a company workplace or
<br>students on Uni-PCs have to work with RKWard but with no root privileges<br>which would make installation of packages "hard". It could be frustrating if<br>somebody can not use this or that because a package is not installed. And I
<br>guess administrators could get annoyed if this happens frequently on many<br>machines. Hope you know what I mean. Someting for the ToDo-list?</blockquote><div><br>I could suggest for this the rkward package for R to have as dependencies the packages needed. I remember Rcmdr if you install with dep=T then installs needed packages, If not however when you open it it says that for Rcmdr to work properly you should install some packages. I do not know if that helps in some way.
