Barplot legend position
Dear useRs,
I'm trying to create a barplot like so:
x=matrix(1:10,2,5)
barplot(x,leg=c("left","right"),besid=T)
The legend is placed in default position topright, however the data are
plotted there too. I tried controlling the legend position by adding
x="topleft" but this results in an error that x matches multiple formal
arguments.
Leaving out the legend

"aggregate" in R
Hi, R users,
I'm wondering how I can aggregate data in R with different functions for
different columns. For example:
x<-rep(1:5,3)
y<-cbind(x,a=1:15,b=21:35)
y<-data.frame(y)
I want to aggregate "a" and "b" in y by "x". With "a", I want to use
function "mean"; with "b", I want to use function "sum". I tried:

set condition in R
Hi, R users,
I'm using while() in R to set a condition. My condition is: i<523 or i>535.
How should I write this in R? I try "while (i<523 or i>535)" and it does not
work. Thanks.

how to predict dynamic model in R
I have a dynamic time series model like this:
dyn$lm( y ~ lag(y,-1) + x + lag(x,-1)+lag(x,-2) )
I need to do an out of sample forecast with this model. Is there any way I
can do this with R?
It would be greatly appreciated if some one can give me an example. Thanks.

How to use "subset" in lm function
Hi, I'm using R to do a time series analysis. In the model, I use the lags
of some variables. such the lags of the variables have different length, I
just can't use them directly in the lm function. Intuitively, I feel that
"subset" might be useful, but I do not know how to use it. Anyone can give
me an example syntax? Thanks.

reduce the size of points in plot???
Hi, R users,
Can anyone tell me how I can change the size of points in my plot?
For example:
x <- c(1,3,6,9,12)
y <- c(1.5,2,7,8,15)
plot(x,y,pch=20)
How do I reduce the size of those points?
Thanks.

identify an element in a column
Hi, R users,
I'm wondering if I can identify an element in a column by an element in
another column. For example:
x<-1:10
y<-11:20
z<-cbind(x,y)
z
x y
[1,] 1 11
[2,] 2 12
[3,] 3 13
[4,] 4 14
[5,] 5 15
[6,] 6 16
[7,] 7 17
[8,] 8 18
[9,] 9 19
[10,] 10 20
What I want to do is: when x=5, y=y-1
Anyone can tell me how to do this? Thanks.

mapping of colornames into hsv: half way done
Ok,
now we have the mapping of color names to color codes (see below) and
conversion to rgb (something like Ben Bolker's function), but how to convert

memory limit in R
Hi, all, I'm doing a discrete choice model in R and kept getting this error:

why summary() does not work here???
Hi, R users,
I'm using the function "vglm" to estimate a multinomial logit model. Every
time I use "summary()" to ask for the coefficients and std error, I got
this:

Anyone know what's wrong here? Thanks.

Question about many-to-one merge
I have spent a whole afternoon searching for the solution, but got nothing so
far. It should be a simple problem.
I have two datasets to merge. The first one just contains two ID columns and
it looks like:
FromID ToID
1 2
1 3
2 1
2 3
3 1
3 2
The second one contains a ID column and a variable:
ID X
1 100

Share names causing big troubles
I work for a school dist, and I am having a bit of trouble with the "Student
Server" We have about 3000 students all with their own accounts. I had the
samba server setup to share their home directories but their home
directories are the same as their login name. So jamie.mcparland would be an
example of a share name. But in Win 9X it gets truncated to jamie.mcparla
then we get the error

Is there a way to change the position of the legend created in a barplot

[LLVMdev] ATS workaround for Clang 3.5
The ATS community is having trouble with clang. They had been using
an older version of clang and upgraded because newer versions give
higher quality warning messages. Unfortunately, with 3.5, moving from
-O1 to -O2 triggers a crash on startup in the clang-generated
executable. I had suggested building with -fsanitize=undefined and
-fsanitize=address to weed out any dependencies undefined

Strange problem with samba
Hi,
I was using samba 2.0.7 veersion for a while without any problem. This
morning, suddenly, many windows (nt/98) cannot connect the samba server
on our Linux (RedHat 6.2) server. Then, I downloaded the version 2.2.4,
extracted, configure it, make, make install according to the document.
Then I test it by running
./testparm
it lists all of shared folders. Then, I run

How to transform the Matrix into the way I want it ???

Generate Random Draw from Gamma Distribution Re: Monte Carlo Simulation in R...
Exactly! Thanks, Duncan.
Let me re-phrase me question like this:
1) X_i values are independent Gammas, with the shape 0.067 and scale 0.008
2) Min(X)=1 and Max(X)=85
3) SUM(X)=2000
4) Do I also have to define the number of draws? if yes, it could be 250.
Based on these restrictions, I want to generate random draw. I'm wondering
how I can do this in R. Thanks.
