Hi Experts,
I am new to R, and was wondering how to do 3D linear
regression in R. In other words, I need to Fit a
3-Dimensional Line to Data Points (input).
I googled before posting this, and found that it is
possible in Matlab and other commercial packages. For
example, see the Matlab link:
We write manuals so that you can know how to do things in R. Package
installation is covered in the 'R Installation and Administration' manual.
We don't have the attachment, but assuming this was a source package I
sugest you look into Uwe Ligges' win-builder service mentioned in that
manual

Oh, please: that is a warning, not an error and not a problem!

I ran across this problem when playing with ccf().
Its function call is

Internally, ccf() calls plot(), which digs up plot.acf() whose

Thankyou the curl-devel installation helped solve the error with RCurl and
GEOquery.

Thank you, Brian and Mark,
I tried the win-builder on http://win-builder.r-project.org/. Is this what
you mean? I uploaded the source code, and I didn't get any email after
couple of hours. It should arrive after half an hour, as it is said on the
webpage. Do you know what can happen?

Hi
I am trying to find a parametric bootstrap confidence interval and when I used
the boot function I get zero bias and zero st.error? What could be my mistake?
Thank you and take care.

Hello
I have a Mac OS X 10.4.5. I am trying to build a 64-bit R by following the

I am using the boot function in boot package. I am facing a problem in getting
the values of bias and st.error in the output.

Hello
I haven't found better instructions, it's just
not an easy thing to do.
You might also consider joining the r-sig-mac group
and reviewing threads there for additional information.
Rather than try to configure, make and install with
one giant command, I'd suggest breaking the task down

Indeed, the call you pass to playwith() must be a self-contained plot
function. Try one of these:
playwith( {plot(x,y); abline(lm(y~x)} )
playwith(plot(x,y, panel.last=abline(lm(y~x
playwith(xyplot(y ~ x, type=c(p, r)))

This gets you close to what you want. The 31/33 are row names that
you can extract and store as actual columns,
x - list('1995'=list('31'=1, '33'=2), '2006'=list('31'=3, '33'=4))
y - lapply(names(x), function(.L1){
+ cbind(as.numeric(.L1),do.call(rbind, x[[.L1]]))
+ })

Hi
I have 3 vectors, say g1, g2 and f, where g1 and g2 contain the row and column
indices of a matrix, with corresponding elements in f. How can I create a
matrix containing the values in f ?
For example:
g1 g2 f
3 4 10
2 1 30
4 4 50
How can then get a matrix that looks as follows:
