You might prefer boxplot(insolation~veg_type) as a graphic.
That will
give you quantiles. To get the actual numeric values you could
for (i in levels(veg_type)) {
print(i)
quantile(insolation[veg_type==i])
}
see ?quantile for more help.

Hello all R-users
_question 1_
I need to make a statistical model and respective ANOVA table
but I get distinct results for
the T-test (in summary(lm.object) function) and
the F-test (in anova(lm.object) )
shouldn't this two approach give me the same result, i.e
Fellow R Enthusiasts..
I'm trying to compile R on AIX 5.2 32bit with gcc 3.3.2-5. I've
tried both the development bundle R-devel_2006-01-25.tar.gz and the
R-beta.tar.gz from about a month ago. In each instance, I'm using the
following options prior to running ./configure
Hi R users
I like to generate random numbers from the logit-normal distribution.
Are there available simple commands I can use?
I used to generate using
exp(rnorm(1000,0,1))/(1+exp(rnorm(1000,0,1)))
I am looking for a simple command such as rnorm().
Thanks in advance
TM

Hi all,
I am wondering what's wrong with my following code?
x=read.table('c:\\.txt');
Error in file(file, r) : unable to open connection
In addition: Warning message:
cannot open file 'c:\.txt', reason 'No such file or directory'
what's wrong?
Thanks

The error message seems pretty clear in this case. It can't
find the file. Try this instead:
x - read.table(file.choose())
and then use the resulting GUI to locate the file.

Hi R users
I like to extract lower diagonal elements of a matrix in such a way like,
data[1,2], data[1,3],
, data[5,6] are extracted from a matrix called 'data'
This short script below is what I have written so far.

Hi R users
Is there any function or command for measureing computation time?
For example, if I like to how long it takes to generate 10 random
numbers from a normal
distribution, Is there any command I can wrap up around rnorm(10,0,1)
and returns time
in a sec unit ?
Thanks

Hi all,
I am using xyplot (lattice) to generate a figure like Figure 4.18 in
MASS4, but I have the following two questions (1) how to change the font
of x(y)lab? (2) how to plot the panels for each level of the conditional
variable (a factor in my data set) in the order as occurred in the
