I would re-install Rtools, and make sure C:\Rtools\bin appears first in
your PATH.

cygwin1.dll problems when installing packages from source
Hi,
As far as I can see, no.
On checking, I have confirmed that the only location of
cygwin1.dll is :
C:\Rtools\bin
Thanks

symbolic computing example with Ryacas
Hi all,
I am trying to implement the following matlab code with Ryacas :
syms U x x0 C
d1=diff(U/(1+exp(-(x-x0)/C)),x);
pretty(d1)
d2=diff(U/(1+exp(-(x-x0)/C)),x,2);
pretty(d2)
solx2 = solve(d2 == 0, x, 'Real', true)
pretty(solx2)
slope2=subs(d1,solx2)
I have tried the following :
library(Ryacas)
x <- Sym("x");U <- Sym("U");x0 <-

Annotation Ticks on the axis
Hi all,
I would like to have help in getting annotation ticks (corresponding to the
minor grid) on my plot. Here is my toy example :
par(mar=c(5, 6, 5, 5) + 0.1)
x<-1:10
y<-x^2
plot(x,y,log="xy",xlab="log(x)",ylab="log(y)")

overlaying points and lines on a surface3d rgl plot with axes
Hi R users and experts,
I am interested in learning more about the use of 3D plots. Specifically, I
want to add points and lines to a surface plot. And get the axes and labels
plotted also. Here is what I have tried with an example data set :
library(rgl)
vol2 <- 2*volcano # Exaggerate the relief
library(reshape)
mvol2 <- melt(vol2)
str(mvol2)
# First, persp and persp3d plots do not succeed

Hi all,
I am having some problems in updating some packages from source. I start
with :
install.packages("Boom",lib="C:/RownLib",type="source")
I get the following error message :
* installing *source* package 'Boom' ...
** package 'Boom' successfully unpacked and MD5 sums checked
