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
ifelse(val3 = "Monthly", val = val1, val2)
I get following error

preparing data for barplot()
What is the best way to produce a barplot from my data? I would like
the barplot to show each person with the values stacked
val1+val2+val3, so there is one bar for each person When I use
barplot(data.matrix(realdata)), it shows one bar for each value
instead.
To post here, I created an artificical data set, but it works fine.

a problem in random forest
Hi, there:
I spent some time on this but I think I really cannot figure it out, maybe I
missed something here:
my data looks like this:
> dim(trn3)
[1] 7361 209
> dim(val3)
[1] 7427 209
> mg.rf2<-randomForest(x=trn3[,1:208], y=trn3[,209], data=trn3, xtest=val3[,
1:208], ytest=val3[,209], importance=T)
my test data has 7427 observations but after prediction,
> dim(mg.rf2$votes)
[1] 7361 2
which has the same length as my training data.
but if I use

print table on plot
Hello,
I would like to be able to plot an array on a plot, something like:
|arg1 | arg2 | arg3
val1| 0.9 | 1.1 | 2.4
val2| 0.33 | 0.23 | -1.4
val3| hello| stop | test
I know Rwave is good to report but don't want to use it.
? Is there a package that allow quick and dirty plot of dataframes like this
?
Thanks a lot

Dear all,
I want to calculate mean values for multiple rows:

Basic Question on Keys/Values
As a java programmer, I'm having issue conceptualizing the following use
case:
Given an value, passed into a function, how do I pull out the lookup?
Ie.
A list of keys (key1, key2, key3)
A list of values (val1,val2,val3)
I want to write a function (or is there something built in?) such that
Callit <- (thekey) {
(magic happens here)
Return value
}
Any ideas?
Thanks a bunch!

Looking for easy way to normalize data by groups

Time = rep(c(0, 0, 0, 0, 30, 30, 30, 30, 60, 60, 60,
60), 3),
Dset = rep(c(1, 2),18),
Val1 = rnorm(36),
Val2 = rnorm(36),
Val3 = rnorm(36),
Val4 = rnorm(36))
You can plot the data nicely with x=Time and y=Val1 by grouping PID and
facetting for Dset.
p <- ggplot(df) +
geom_line(aes(x=Time,y=Val1,group=PID)) +
geom_point(aes(x=Time,y=Val1,colour=PID)) +

[LLVMdev] ARM assembly
Hi All,
I am working to cross compile (just generate assembly code) a simple C code
in ARM. First, I use CLANG to get LLVM bytecode, then I use llc to generate
assembly for ARM. The problem is it never uses any other register except
r0-r3 and always uses spill code even if other register are available to
use. Anyone has any idea?
Thanks

Setting Multiple Values via func_odbc ...?
...MySQL, but that's a pain in the ass because the asterisk-addons package has no default rpm spec file for building an RPM.
I had something like this in func_odbc.conf:
[VOX_LOG_CALL_LEG]
dsn=MySQL
write=INSERT into CallLog (Source,IDDCode,AreaCode,ProviderId,SIPReply) values (${VAL1},${VAL2},${VAL3},${VAL4},${VAL5})
but it doesn't like it. In order for this to work, I'd have to have several LOG_CALL_LEG functions, each taking one parameter, and then requiring several database updates!

[LLVMdev] [RFC] Attributes Rewrite (Final)
...This is the final proposal for the language changes. There isn't a lot of new information except for the syntax changes for the new feature.
Executive Summary:
The new syntax is:
#0 = attributes { noinline align=4 "cpu"="cortex-a8" }
#1 = attributes { attr = (val1 val2 val3) }
#bork = attributes { sspreq noredzone }
define void @foo() #0 #bork { ret void }
The 'align' and "cpu" attributes both have a value associated with them. The 'attr' attribute in '#1' has multiple values associated with it. (The BNF is below in the 'IR Ch...
