Hi
I am trying to add a less than equal sign to a plot. I have previously done
this using unicode but is not working in this instance. Any suggestions
would be great
thanks
example code:
library(ggplot2)
df<-data.frame(vis=c(0,0,1,1) , count=c(10,15,20,10) , grp=c(0,1,0,1))
df$grp <-factor(df$grp ,levels=c(0,1) , labels =c("x \u2265 10" , "x > 10"))

ggplot - adding regression lines
Hi
I am using ggplot to overlay two regression lines on a scatter plot each
corresponding to a treatment group.
The default plot gives a different slope for each treatment group. However,
in some cases i want the lines to be parallel -ie no significant
interaction.
My code:
ggplot(data=df,X,Y,colour=treatment) + geom_point() +
geom_smooth(method="lm")

I want to extract elements of elements in a list.
Here's an example of what I mean:
If I create a list:

x[[loop]] <- summary(runif(100))
}
> head(x)

Why replacement has length zero? And How can I fix it?
Hi
for the loop section runif needs curved brackets
Try
IAP <-NA
for (i in 1:Sample.Size){
if (DataSet$SES[i]>0) {
IAP[i] <- ifelse(runif(1)>0.75, 1, 0) # High SES, higher chance to be in
Treatment #
}
else {
IAP[i] <- ifelse(runif(1)<=0.25, 1, 0) # Low SES, lower chance to be in
Treatment #
}
} # End loop #

update() can not find objects (PR#1861)
Full_Name: Yi-Xiong Zhou
Version: 1.5.1
OS: win2000pro
Submission from: (NULL) (64.169.249.42)
Update() can not find objects when it is used in a function, which is in turn
being called by another function. Here is a R script to show the problem:

Applying 'cbind/rbind' among different list object
Hi, I am wondering whether we can apply 'cbind/rbind' on many **equivalent**
list objects. For example please consider following:
> list1 <- list2 <- vector("list", length=2); names(list1) <- names(list2)
<- c("a", "b")
> list1[[1]] <- matrix(1:25, 5)
> list1[[2]] <- matrix(2:26, 5)
> list2[[1]] <- 10:14
> list2[[2]] <-

how to get a primitive function object
Hi,
I want to create an alias for the "<-" function and then later
overwrite it. Any idea how I can get the "<-" function object? I know
for other functions it's easy, something like "f <- seq" will do; how

automatic selection of object without loop
Hello,
does anyone know the solution to this problem:
I imported a dataframe from Spss into R and saved it as an object called

I have got the following command lines:

l1 <- q0007_0001_l
now i would like to be able to change the column name in the first command
line (e.g. into q0007_0002) and to get R to automatically

[LLVMdev] tbaa
Hi,
Could anyone tell me how exactly do I use "Type Based Alias Analysis"?
I compiled the C program with Clang, and verified that there is tbaa
metadata in the IR code.
But then when I use "opt -tbaa input.c.bc -aa-eval" to check the results,
it always gives 100% may aliasing no matter what input.
Am I using "tbaa" correctly?
Thanks.

[PATCH v1] cover: armv7: celt_pitch_xcorr: Introduce ARM neon intrinsics
Hi,
Optimizes celt_pitch_xcorr for ARM NEON floating point.
Changes from RFCv3:
- celt_neon_intr.c
- removed warnings due to not having constant pointers
- Put simpler loop to take care of corner cases. Unrolling using
intrinsics was not really mapping well to what was done
in celt_pitch_xcorr_arm.s
- Makefile.am
Removed explicit -O3 optimization

I've got stuck when trying to replace values in a vector by selecting
