Dear "rkward" Team,             [0] Observing (partly) what one subpage (https://rkward.kde.org/Contact) of your project recommends, I am sending you herewith the output of "rk.sessionInfo()" (date of calling this function in "rkward" R console: 3rd March 2016)        -------START OF OUTPUT-------RKWard version: 0.6.1KDE version (runtime): 4.13.3KDE version (compile time): 4.10.3Local KDE directory: /home/ichhalt/.kde/RKWard storage directory: /home/ichhalt/.rkward/Debug message file(s) in use (these may contain relevant diagnostic output in case of trouble):/tmp/rkward.frontend.n17001/tmp/rkward.rbackend.J17010R version (compile time): 3.0.0  (2013-04-03 r62481)R runtime session info:R version 3.0.2 (2013-09-25)Platform: x86_64-pc-linux-gnu (64-bit)locale: [1] LC_CTYPE=de_DE.UTF-8          LC_NUMERIC=C                  [3] LC_TIME=de_DE.UTF-8           LC_COLLATE=de_DE.UTF-8        [5]

Please note that I am not consciously using html format for emails under this address (as I was recently briskly feed-backed on), text-only mode is not available to and thus unapplicable for me thus far.        [a] I decided to delve into statistical programming language R in 2015, seeking to get a properly embeddable R GUI. Since 
"rkward" was described to be suitable for R on a Linux system (mine: current Debian-flavour "Kubuntu" on a 64bit system) that uses KDE, I
 choose the product you developed (current and still running version: 0.6.1).       
 [b] In the meantime, I came across some problems concerning R package 
and/ or R version update that are by now apparently irresolvable. R package 
update via R console of "rkward" seems to be/ have gone defective:        
 [b1] that is on entering the respective command 
("install.packages(packageName)"), "rkward" R console either gives back 
it (1); could not find the mirror or (2); the very R package is 
unavailable for R version 3.0.2. Without the latter error message, I 
would not have wanted to very early learn about the uggly fact that I do
 not really know which (bulk of) package(s) to replace to finally 
update/ upgrade R to a higher version number-and whether "rkward" could perform such a task.         [b2] Now that R
 version number approaches 3.5, I intend to better learn about the 
problems I have no oversight over so far. It is high time to determine how to 
'liberate' R from some constraints I experienced as (3); using "rkward" R
 console instead of R-within-bash console resulted in unforeseen (non)results when some commands were not 
yielding what logically and normally they would have had to 
deliver. I was told (via email exchange with) by an author of a a fairly instructive R book, Mr 
Norman Matloff, that the GUI had not full take on R (he put it something like that there was something "masked") as it could and 
should have if all the intrinsic prerequisites of the respective book 
examples were fulfiled.        [c] Hence, I would like to know 
whether there is already awareness of this (bunch of) issue(s) and/ or 
whether there existed a (projected) resolution to this problem. I am also and still a beginner in Linux which would require me to have some guidance on working my way out in an bash-only style (or, alternatively, how one would have to proceed when using the fine-tune package manager "Synaptic"). I can, additionally, 
vaguely remember that a pop-up window during the installation process of
 "rkward" and/ or "R" on my system said something like "originally only 
conceived to run on lubuntu"-maybe that is the "source of all evil"...        [d] As I have, (un)fortunately, seen some moments ago 
on the rkward home page, version 0.6.4 is available for installation. 
Would, thus, a higher "rkward" version's installation heal the problems (and make descriptions given by me in paragraphs [b1] and [b1] obsolete) of an "rkward" version unfunctionable when it comes to 
updates "the regular way"?        [e] Thank you very much in advance.           Best regards,        Markus Hofstetter
