variable labels to accompany data.frame
Often it is useful to keep a "codebook" to document the contents of a dataset. (By "dataset" I mean
a rectangular structure such as a dataframe.)
The codebook has as many rows as the dataset has columns (variables, fields). The columns (fields)
of the codebook may include:
? variable name
? type (character, factor, integer, etc)
? variable label

Dump the "source code" of data frame
Dear R experts,
I remember a similar function existed and have been mentioned in
R-help before. I tried my best to search but I really can't find it
out.
suppose I have an data frame like this:
> somedata <- data.frame(age.min = 1, age.max = 1.5, male = TRUE, l = -1.013, m=16.133, s=0.07656)
In order to back up the data and I don't want to use write.table(), I
would like to back

conditional plot
Hi,
Can anyone pls help me in plotting the following data?
The data-set contains company name, specification-1, specification-2.
The graph would basically plot company name with specification-1
on x-axis, & specification-2 on y-axis.
Simply put - company name should get classified into one of the
four quardrants created by specification 1 & specification2.
Thanks.

Vector Manipulation
Dear All,
For any given vector, I want to extract a sub-vector such that the new vector skips all zeros, if any , at the start of vector. Is it possible to achieve this w/o looping?
E.G : > x = c(0,0,1,2,3,4,5,0,0,8,9)
> y = somefunc(x);
> y
[1] 1 2 3 4 5 0 0 8 9

Note: "The default device has been opened to honour attempt to modify trellis settings"
R-help,
I'm using a function whose end result is a trellis plot.
When I call the function I get sometimes the following message:
"Note: The default device has been opened to honour attempt to modify
trellis settings "
leading up to any plot whatsoever.
I call the package 'lattice' within the function and 'detach' after
plotting.

[LLVMdev] LLVM ERROR: expected relocatable expression
Hi Eli,
Slightly changed the example :-
.section somedata
.Ltmpa:
.word 100
.Ltmpb:
.word 60
.Ltmpc:
.word 40
.Ltmpd:
.word (.Ltmpa-.Ltmpb)-.Ltmpc
The GNU assembler properly handles the above.
$as -c x.s -o x.o
$readelf -x 4 x.o
Hex dump of section 'somedata':
NOTE: This section has relocations against it, but these have NOT been
applied to this dump.

You should use make -j with a number lower than 4, it looks like you ran
out of memory when linking.

How can I eliminate a loop over a data.table?
I've two data.tables as shown below:
***
N = 10
A.DT <- data.table(a1 = c(rnorm(N,0,1)), a2 = NA))
B.DT <- data.table(b1 = c(rnorm(N,0,1)), b2 = 1:N)
setkey(A.DT,a1)
setkey(B.DT,b1)
***
I tried to change my previous data.frame implementation to a
data.table implementation by changing the for-loop as shown below:
***
for (i in 1:nrow(B.DT)) {
for (j in nrow(A.DT):1) {

Help with a loop
HI:
I need ideas on how to make this code shorter (maybe with a second loop?).
The code as it is works, but in this case I only have 14 samples, but it
will become insane with more, so I need a way to make it more automatic. The
problem is that the output from ts1, ts2, and so on is a vector with more
than one value, so I do not know how to solve this.
Thanks

color of lines while printing through for loop
I am trying to find a convenient way to control line colors when
printing from a for loop using the lines command.
Right now I have solved this by creating a colors vector that is refered

1,2,3,4,5...
I would like to get colors from the col = rainbow(x) that you can use in
plot() and set the to be my number of lines (I think
