Subject: Re: [R] About .RData
Furthermore can I run following command on R?
rm /home/userA/.RData
.RData contains all of the objects in a workspace (your data,
functions etc.). If you start R in a directory that contains a .RData
file it will be loaded automatically.
If you delete the file you are deleting your data.
Does that answer your question ?
Hi Michael,
Thanks for your advice
Windows 7
Ubuntu 10.04
(both 64 bits)
I have Windows R and Linux R running on VM (guest) of Oracle VirtualBox.
Before I tested ANOVA on Linux R. On existing R - q(), I
mistakenly typed y resulting in the file .RData created (I
suppose). Thereafter on starting R the line "[Previously saved
workspace restored]" is displayed.
Running;
list.files(getwd(),full.names=TRUE,all.files=TRUE)
[1] "/home/satimisub04dk01/."
[2] "/home/satimisub04dk01/.."
[3] "/home/satimisub04dk01/.adobe"
....
....
[41] "/home/satimisub04dk01/R"
[42] "/home/satimisub04dk01/.RData"
......
[54] "/home/satimisub04dk01/.xsession-errors.old"
- end -
On Windows R
Starting R doesn't have the abovementioned line displayed.
list.files(getwd(),full.names=TRUE,all.files=TRUE)
[1] "C:/Users/Administrator/Documents/."
[2] "C:/Users/Administrator/Documents/.."
[3] "C:/Users/Administrator/Documents/AOD_V3010287_XpVistaWin7.zip"
[4] "C:/Users/Administrator/Documents/ASUSUpdt_V71702_XPVistaWin7.zip"
[5] "C:/Users/Administrator/Documents/Default.rdp"
[6] "C:/Users/Administrator/Documents/desktop.ini"
[7] "C:/Users/Administrator/Documents/EPU_V10022_XPVistaWin7.zip"
[8] "C:/Users/Administrator/Documents/ExpressGate_v14910_Patch.rar"
[9] "C:/Users/Administrator/Documents/M4A78T-E-QVL.zip"
[10] "C:/Users/Administrator/Documents/MB_WIN7_ATK.ZIP"
[11] "C:/Users/Administrator/Documents/My Music"
[12] "C:/Users/Administrator/Documents/My Pictures"
[13] "C:/Users/Administrator/Documents/My SAS Files(32)"
[14] "C:/Users/Administrator/Documents/My Videos"
Now my questions are;
1) After deleting .RData on Linux R whether the abovementioned line
will not popup again?
2) Why on Windows R the path of the folders/directories shows the
Administrator;
[1] "C:/Users/Administrator/Documents/."
......
???
Not the user? I login as user.
A further thought, I recall that I login as Administrator to
install R. Does it matter?. How to change the path back to user?
You probably set the startup directory in the shortcut when you did
the install. (I believe that's the default behaviour.) So you need
to edit the shortcut to a different directory, possibly with a
separate shortcut for each user. The editing is done through
Windows, by right-clicking on the shortcut.
Duncan Murdoch
I find it is best to tell R when i install it _not_ to supply a
shortcut and then as Duncan suggests establish one myself as the
user. The alternative is to set the permissions so you can reset the
startup directory within the shortcut.
TIA
B.R.
