reshaping issue
Dear R users,
I have a problem with reshaping data. I know such questions have been asked before, but I can't get it right, neither with the reshape function nor with the melt function.
My dataset has about 407 variables and about 48000 cases.
Each case looks as follows:
V1 v2 v3 v4 v5 v6 v7 x1 y1 x2 y2 .... x200 y200
V1 is unique, v2-v7 are

Applying rbind() to a sequence of data frame names
I have a set of data frames ds1, ds2, ... each having the same columns
and column names:
ds1 <- data.frame(x=c(1,2,3,4), y=c(5,6,7,8))
ds1 <- data.frame(x=c(9,10,11,12), y=c(13,14,15,16))
...
and I would like to combine them into just one data frame like
ds <- rbind(ds1, ds2, ...)
Because there are so many of them, I will have to use a character array

from list to dataframe
I was wondering if someone can help me figure out the following:
I have two patient datasets, ds1 and ds2. ds1 has fields "patid", "date",
and "lab1". ds2 has "patid", "date", and "lab2". I want to find all the
patids that have at least 2 dated records for each lab. I started by
splitting each dataset by patid, to create ds1.list

plotting predicted curves with log scale in lattice
Hi,
I was taken off guard by the following behavior in a lattice plot.
I frequently want to add a predicted curve defined at more
points than in the formula expression of xyplot. There have
been numerous examples of how to do this on r-help, but I
still often struggle to make this work. I just realized that
specifying one of the axes on a log scale does not guarantee
that the added data for a

How to make legend with line+ character
Dear all,
I have a multiline plot with each line labeled with a different letter.
But I'm not able to make the legend display the same kind of pattern
'-a-', instead the letter is overwritten by the line. A simpler legend
with only the letter is not very visible and the pt.bg does nothing with
letters. Any idea?

xyplot - help with multiple Y's vs. X of a member data in multiple panels
Dear R experts,
Wish you all a HAPPY NEW YEAR!
How do I go about plotting (using lattice) overlays of an ID (group=ID)
observed, fitted data in each panel of a multiple panel plot (each panel
identified by DS1 + DS2 + DS3)? "x" variable is X1 in the accompanying
section of a dataset. each individual is identified by color and Y's are
identified by "pch" or "lty".

[LLVMdev] vmkit on x86_64
Hello,
I'm trying to compile vmkit on a x86_64 linux box with gcc-4.1.2, but
I'm running into troubles because of various problems with casts
between pointers and integers. Is there anybody who succeeded in this
task? Az I see, some of the problems can be fixed with an appropriate
typedef/macro declaration, but in VMCore/JavaObject.cpp some lowlevel

How to use conditional statement
Dear R helpers
Suppose
val1 = c(10, 20, 35, 80, 12)
val2 = c(3, 8, 11, 7)
I want to select either val1 or val2 depending on value of third quantity val3.
val3 assumes either of the values "Monthly" or "Yearly".
If val3 = "Monthly", then val = val1 and if val3 = "Yearly", then val = val2.
I tried the ifelse statement as

Memory Store/Load Optimization Issue (Emulating stack)

Getting group size in a data frame
Hi all,
I have a data frame with some measured values of some animals. Sometimes the
measurement failed, resulting in a NA for a measurement and sometimes the
animal died, resulting in NA for all measurements.
I have several groups of animals. How do I find the size of each group with
only alive animals? And how do I find the size of the groups for each
measurement?
An example:
