Subtitle?
Hi,
Is it possible to add a subtitle that appears directly below the main
title?
I tried the "sub" parameter, but it adds sub-title to the bottom of the
plot.
Cheers,
Kevin

Length of a string
Hi,
Suppose I have created something like this in R:
foo <- "myfoo"
and I want to find out the number of character in foo (in other words, R
should return 5 since "myfoo" has 5 charactors.
How can I do it? I tried:
length(foo)
but it returned 1.
Cheers,
Kevin

Re: Writting R Function
Hi,
I think I found the problem. It lies in my Fortran program. Is there a
way, after a DO loop, to make sure it does NOT return anything?
Cheers,

Overall Title in par(mfrow)
Hi,
Say I did something like:
par(mfrow = c(1, 2))
plot(1:10)
plot(1:10)
and I'd like to have an overall title, i.e. a title that would appear,
centered, on the top of both plots, rather than the top of the last plot.
I tried:
title("FOO", outer = T)
but it doesn't appear right. Half of the FOO is outside the figure region
and can't be seen...
Is there another

More on list to data frame (was: Re: List to Data Frame
Hi,
Now suppose I have just one list called FOO, which has 25 objects, e.g.:
[[1]]
1 2 3 4 5
[[2]]
6 7 8 9 10
.
.
.
And I want to do something like:
FRED <- data.frame(cbind(unlist(FOO[[1]]),
unlist(FOO[[2]]),
# ... for all 25 subsets
))
Is it possible to do this, without doing unlist(FOO[[i]]) 25

xtable()
Hi,
Does anyone know how to manually configure the number of digits printed
out from xtable()?
For example, I'm exporting a data frame through xtable() into a LaTeX
table, I only have two columns in the data frame so by default I only get
two decimal places. But I'd like at least 5 decimal places.
I had a look at ?xtable() but can't seem to find an example.

barplot()
Hi,
Is it possible to draw barplot with x-axis being shown? I looked up the
help file and I couldn't seem to find it.
For example, I tried to do
x <- 1:9
p <- log10(1 + 1/x)
barplot(p, xlab = "Digit d", ylab = "Probability",
ylim = c(0, 0.35), axes = F,
main = "Benford's Law Probability")

More on for() Loop...
Hi,
Say I want to do something like fitting 10 different sized trees with
rpart() function. The only modification I need to do is to set 10
different cp's, which I have in a vector called foo.
Can I do something like:
for(i in 1:10) {
rpart(y ~ ., cp = foo[i], data = mydata)
}
My problem is, I wish to save the 10 rpart objects into 10 different
names, my.rpart1 ~ my.rpart10, for

Using Object's Name in Function
Hi,
Suppose I have a function:
myfunc <- function(x, y) {
...
}
And within the function I want to print out the name of the x, y
vectors. For example, if I do:
> myfunc(foo, goo)
[1] "foo" "goo"
It shall return "foo", "goo" (with or without quotes is fine), where foo
and goo are two vectors with numbers.
I know this sounds strange, but I'd

A Very Trivial Question
Hi,
This is a very trivial question, and I do not know why I cannot remember
the answer at all!
How does one get the entire system information (which OS, R
version....etc) using an R command?

Time Series ts() Objects
Hi,
Is it possible to create a ts() object, whose data is daily based BUT
measured only on working days?
In other words, suppose I have a data set with 255 observations, measured
from 29 June 1959 to 30 June 1960. How would I create such a data? I
tried something like:
ts(c(...), start(1959, 180))
but I'm not sure what to use for frequency. In other words I don't know

compling C code in R for Windows
I have used Splus 3.4 for UNIX and I have a C file that I compiled using
"Splus COMPILE" and later called with dyn.load() and .C(). It works in Splus.
I want to do the same thing in R, as in just use my .s and .c files and
find the equivalent of "Splus COMPILE". I've ran into lots of problems
trying to do this in Windows so far, so please help!

This is a simple question with if elseif....however I am having trouble

Suppose I have a data set with 3 variables, a, b and c say. Let's say c

MASS Library
Hi,
I was just trying out an example on Page 247 of the MASS (Modern Applied
Statistics with S-plus) book and saw the function "negexp.ival".
It says it is supplied in the MASS library, however when I load the
library in R and typed:
negexp.ival
it says:
Error: Object "negexp.ival" not found
Does it mean it only appears in the MASS library for S-plus?

Rounding
Hi,
Suppose I have:
459
1789
23590
and I'd like to round them to:
400
1700
24000
On the other hand, say if I have:
232
1234
23120
that need to be rounded to:
300
1300
24000
I tried the round(), floor() or ceiling() and can't get what I want. Is
there any tricks I can use to achieve this goal?
