Anomaly in MIN (MAX) ?
...R (0.64.1):
min(c(NA,NA,NA),na.rm=T)
returns the following
Warning in min(..., na.rm = na.rm) : no finite arguments to min/max;
returning extreme.
[1] 2147483647
S-Plus 4.5( Win32 edition)
min(c(NA,NA,NA),na.rm=T)
returns
[1] NA
The S-PLUS behaviour seems to be the right one
Thanks,
Athula.

Pivoting a data.frame
...6 NA 0.1 NA
[Data Frame 22]
As you see above, the columns of Table 1 is rearrange to
categorise the third column (in terms of Col1 and Col2).
I wonder whether anybody here could help me to code this
in S-Plus or R, or point me on the direction how to do
this.
Many Thanks,
Athula.

Change of parsing parameters to functions between 0.63.1 and 0.63.3 ?
...-> NA NA x[b]-> NA NA
Obviously, something is not right. I have verified this in both Unix
(Solaris, Linux) and also on WinNT
However, R Version
Version 0.64.0 Unstable (February 4, 1999)
Reports a similar behaviour to Version 0.63.1 : i.e. giving me the
correct results.
Many Thanks,
Athula

3d surface plot (ideally using rgl package)?
Dear HelpeRs,
I would be grateful for anybody who might help to produce the following
plot (the code for matlab is below) using the "rgl" package of R?
[t,r] = meshgrid(linspace(0,2*pi,361),linspace(-4,4,101));
[x,y] = pol2cart(t,r);
P = peaks(x,y);
figure('color','white');
polarplot3d(P,'colordata',gradient(P));
view([-18 72]);
You may see the code and plot
