Re: [R] Adding 3D points

I would like to add individual points and lines to a persp() plot that I
generated with the geoR package.
See example (2) in ?persp. You must define this function:
trans3d - function(x,y,z, pmat) {
tr - cbind(x,y,z,1) %*% pmat
list(x = tr[,1]/tr[,4], y= tr[,2]/tr[,4])
}
Then you must assign the result of your persp() call to pmat, e.g.:
R x - y - seq(-10, 10, length = 50)
R f - function(x, y) {r - sqrt(x^2+y^2); 10 * ifelse(r==0, 1, sin(r)/r)}
R z - outer(x, y, f)
R pmat - persp(x, y, z, theta=30, phi=30, expand=.5, col=lightblue,
+ xlab=X, ylab=Y, zlab=Z, ticktype=detailed)
And then you can add points and lines:
R points(trans3d(0,0,f(0,0),pmat))
R z2 - sapply(1:length(x),function(n)f(x[n],y[n]))
R lines(trans3d(x,y,z2,pmat),col=red,lwd=2)
R lines(trans3d(c(-10,10,10,-10,-10),c(-10,-10,10,10,-10),c(2,2,8,8,2), pmat),
+col=blue)

More seriously, I seem to recall David Brahms at one time had created an R

be very similar to the S-Plus functions of the same names. The twopass

It's a moving target! I wrote such a list in October 2001, and revised it a
year later, but I haven't updated it since then (I no longer use S-Plus). Some
people (e.g. Paul Gilbert) replied that they also had lists which didn't
overlap much with mine, suggesting we were each seeing just a small part of the
puzzle. So maintaining a complete and current list would be quite a challenge.
Paul also mentioned to me a mailing list R-sig-S on the topic:
https://www.stat.math.ethz.ch/mailman/listinfo/r-sig-s
but it seems dead since May 2001.
That said, here's my year-old list. Note S means S-Plus 6.1.2 (not The S
Language) and R probably means R-1.6.0.
*** R vs. S (DB 10/28/02) ***
Language differences:
- Scoping rules differ. In R, functions see the functions they're in. Try:
f1 - function() {x - 1; f2 - function() print(x); f2()}; f1()
- Data must be loaded explicitly in R, can be attach()'ed in S.
Addressed by my contributed package g.data.
- R has a character-type NA, so LETTERS[c(NA,2)] = c(NA,B) not c(,B)
- paste(a,b, sep=|, sep=.) is an error in R; ok in S.
- for() loops more efficient in R.
Graphics differences:
- Log scale indicated in S with par(xaxt)==l, in R with par(xlog)==T.
- R has cex.main, col.lab, font.axis, etc. Thus title(Hi, cex=4) fails.
- R has plotmath and Hershey vector fonts.
- R has palette(rainbow(10)) to define colors (both screen and printer).
Functions missing from R:
- unpaste, slice.index, colVars
Functions missing from S:
- strsplit, sub, gsub, chartr, formatC
Functions that work differently:
- system() has no input argument in R.
- substring(s,x) - X only works in S, but R has s - gsub(x,X,s).
- scan expects numbers by default in R.
- which(numeric) converts to logical in S, is an error in R.
- The NULL returned by if(F){...} is invisible in R, visible in S.
- The NULL returned by return() is visible in R, invisible in S.
- Args to var differ, and R has cov. S na.method=a ~ R use=p.
- var (or cov) drops dimensions in S, not R.
- cut allows labels=F in R, not in S (also left.include=T becomes right=F).
- Last argument of a replacement function must be named value in R.
- tapply(1:3, c(a,b,a), sum) is a 1D-array in R, a vector in S.
- probability distribution fcn's have arg log.x in R (ref: Spencer Graves)

Version 1.4 of package g.data is available on CRAN. This upgrade is necessary for it to work under R-1.8.0, and is fully backward compatible. Description: Create and maintain delayed-data packages (DDP's). Data stored in a DDP are available on demand, but do not take up memory until requested.

Thanks very much to [EMAIL PROTECTED] for pointing out the incompatibility. (Sorry, Brian, a direct reply to you bounced.) g.data basically creates mock packages (DDP's) to contain the data, and in R-1.8.0 a package needs a DESCRIPTION file to be recognized by .find.package().
