After changing "involuntarily" some of the graphics parameters with
the command par() (I did not know that changes with this command are
permanent), now when I made a plot of the survival Kaplan-Meier
function, the Y axis does not start at 1, and the X axis does starts
at 0. The commands that I use are:
library(survival)
BROWN.SPV = Surv(BROWN$TEMPS, BROWN$DEF)
BROWN.KM = survfit(BROWN.SPV ~ 1)
plot(BROWN.KM$time, BROWN.KM$surv, type="s")
I would be happy to be proven wrong, but I don't think so. My idea is
to add this line to your .Rprofile:
myopar <- par()
Then you can restore in the future with
par(myopar)
(This is untested and at times I fall on my face with initialization
assumptions. If the graphics package is not loaded at the
time .Rprofile is interpreted you might need to run require(graphics)
before that command.)
The usual practice in a console session (if you remember to do this) is:
opar <-par(new-par-specs)
plot-commands
par(opar)
And you should instead be using on.exit if you are writing functions
to do this.
How can I restore previous graphics parameters? Is there a file that
would delete to restore the initial settings (already use R in debian
squeeze)?
