create a '3D line plot'
Esteemed useRs and developeRs,
I need to create a '3D line plot' (proper name?) of which an excellent
example can be viewed here:
http://cococubed.asu.edu/images/87a/images/unknown_pleasures.jpg
I have some experience using the rgl package to create 3D PCA plots, but
have no idea where to start for an image like this.
I'd really appreciate suggestions & help on how might

function to filter identical data.fames using less than (<) and greater than (>)
Esteemed UseRs,
I've got many biggish data frames which need a lot subsetting, like in
this example:
# example
eg <- data.frame(A = rnorm(10), B = rnorm(10), C = rnorm(10), D = rnorm(10))
egsub <- eg[eg$A < 0 & eg$B < 1 & eg$C > 0, ]
egsub
egsub2 <- eg[eg$A > 1 & eg$B > 0, ]
egsub2
# To make this clearer than 1000s of lines of extractions with []

deduplicate mode?
Have you considered to introduce a "deduplicate mode" for
rsync, replacing duplicate files in the destination directory
by hard links?
Of course there might be a lot of problems together with
this feature, but on creating backups it could help to
save a lot of disk space.
--link-dest might be interesting in this context, too.

specifying arguments in functions and calling functions, within functions
Esteemed R UseRs,
Regarding specifying arguments in functions and calling functions
within functions:
## beginning ##
## some data
ex <- rnorm(10)
ex[5] <- NA
## example function
Scale <- function(x, method=c("mean", "median")) {
scl <- method
scl(x)
}
## both return NA
Scale(ex, method=median)
median(ex, na.rm=FALSE)
## both return the median

venneuler() - customize a few things.
Esteemed UseRs and DevelopeRs,
Just coming to terms with the very attractive proportional venn
gernator, venneuler(), but would like to customize a few things.
Is it possible to-
-suppress all circle labels?
-suppress only certain circle labels?
-print specific text strings at specified locations within the circles?
and unions?
-specify circle colors?
-specify label font, size & color?

attempted merge() returns: cannot coerce type 'closure' to vector of type 'any'
Hi Dimtris and esteemed useRs,
I don't understand why i get this error message when attempting to use
merge() -
> temp <- merge(x, y[,17, drop=FALSE], by=rownames, sort=FALSE)
Error in as.vector(x, mode) :
cannot coerce type 'closure' to vector of type 'any'
It should work because:

heatmap.2() yielding an inappropriate key?
Esteemed R-users,
heatmap.2() is yielding an inappropriate key based on my colors and
break-points.
In the reproducible example below, the key is inappropriate (to me) because-
1. 'Orange' is simply not represented in the key, despite its prescence
in the heatmap.
2. The proportions of the key are clearly out, ie., my largest bin, (0.1
- 0.2) is half the range, but this bin (colored

'programatically' list or call objects for use in a function?
Esteemed R users and developers,
How does one 'programatically' list or call objects for use in a function?
For example, i thought i could do something better than this:
save(A.cwb, B.cwb, C.cwb, D.cwb, E.cwb, F.cwb, file="afile.RData")
with something like these-
prfxs <- c("A", "B", "C", "D", "E", "F") #**
