Best practices for writing R functions (really copying)
Gabriel Becker writes:
AFAIK R does not automatically copy function arguments. R actually tries
very hard to avoid copying while maintaining "pass by value" functionality.
... R only copies data when you modify an object, not
when you simply pass it to a function.
This is a bit misleading. R tries to avoid copying by maintaining a
count of how many references there are to an

Multiple cex sizes in main for xyplot?
Folks:
I would like to write two lines of text in two different font sizes (or
faces or ...) as the title ("main") of a trellis plot. The following code
does it, but not well:
xyplot((0:1)~(0:1),
main = textGrob(lab=c("Some Text","Some More Text"),y=c(.95,.8),
gp=gpar(cex=c(1.2,1.0)))
)
There is too much space between the title text and the plot. I assume

rotated labels in barplot with beside=T and multiple groups
I have a data set that I display using barplot. I don't know what you
call it, but when I look at it, it looks like this:

Boxplot with full x-range
Hi all,
I'm new to R, and have the following problem:
I wish to draw a boxplot of simple data in two columns. The x-axis
(taken from first column) is grouped to intervals (using 'cut').
These intervals serve as x-value to the boxplot, and the data from the
second column are the y-values.
The problem is that I want to give an impression of the trend of the data
in the x-range.

Calculated mean value based on another column bin from dataframe.
Dear list,
I have a dataframe with two column as fellow.
> head(dat)
V1 V2
0.15624 0.94567
0.26039 0.66442
0.16629 0.97822
0.23474 0.72079
0.11037 0.83760
0.14969 0.91312
I want to get the column V2 mean value based on the bin of column of
V1. I write the code as fellow. It works, but I think this is not the
elegant way. Any suggestions?

counting the number of elements in a column
Hi All,
I have a column that contains values between 0 and 1. I would like to make
a table that consists of the number of elements in each category.
For example , how many elements have values between 0 and 0.1, 0.1 to 0.2,
0.2 to 0.3,etc??..0.9 to 1.
Is there an easy way to do this?
Thanks

Why does matrix selection behave differently when using which?
Dear R community,
I have a medium sized matrix stored in variable "t" and a simple function "
countRows" (see below) to count the number of rows in which a selected
column "C" matches a given value. If I count all rows matching all pairwise
distinct values in the column "C" and sum these counts up, I get the number
or rows of "t". If I delete the

Error in which()
Hi all,
I'm trying to filter data into respective numbers. For example, if the
data ranges from 0 to <0.1, group the data. And so on for the rest of
the data.
There are inconsistencies in the output. For example, b1[[3]] lumps all
the 0.2s and 0.3s together while 0.6s are not in the output.
Running the function - table(f1) - shows that each of the
components/numbers has x number of
