Subject: R-beta: problem with graphics parameter "fin"


Hi,

I have the following problem (with R 0.61.3 an Linux, and a new and empty
workspace) 

> oldpar<-par()
> par(oldpar)
Error: attempt to set invalid value for graphics parameter "fin".
> oldpar$fin
[1] 6.992034 6.990803

but now:

> oldpar$fin <- c(6.99,6.99)
> par(oldpar)

it works.

It seems, that if I set oldpar$fin to values greater than listed above
(6.9920...) it stops to work:

> oldpar$fin <- c(7,7)
> par(oldpar)
Error: attempt to set invalid value for graphics parameter "fin".

and again

> oldpar$fin <- c(6.992034,6.990803)
> par(oldpar)
Error: attempt to set invalid value for graphics parameter "fin".

What does the par() values depend on? the X Server? 
It happens both on an 8bit and 24bit XFree display. 

It occurs also with no active x11() device (postscript() instead).

What's the matter? I tried the same on the DEC Alpha (but with R 0.61.1
!!) and it didn't happen. 

Sorry, but I have no more R 0.61.1 available on Linux, so I could not 
check it with an earlier version.

PS:
It does not appear with the R snapshot (from May 16).
