I humbly suggest adding the fonts argument
to the list of arguments recognized and processed
by ps.options.
Here is my argument:
Currently, in Sweave it seems to be impossible
to use multiple font families in <>
code chunks without additional moderately inconvenient
coding.
The problem is that it
I propose that a 'value' argument be added to
'lower.tri' and 'upper.tri'. This is analogous to
the 'value' argument of 'grep'.
Something like the following should work:
> upper.tri
function (x, diag = FALSE, value = FALSE)
{
x <- as.matrix(x)
if (diag)
ans <- row(x) <= col(x)
Hello,
anybody knows dev.copy() usage?
I'm developing a GUI for R, and at some time when I have a plot, I want to
save it as a pdf. dev.copy() is , I think, what I need as well as open a
pdf() device.
I have read lot of times help(dev.dopy) but It's a little difficult to
understand :S
Any idea?
Reading the following delimited file with read.csv() or read.table()
file1:
X,Y
1,2
2,4
3,6
4,8
5,10,,
6,12
produces a data.frame with 7 rows instead of 6 because the two extra values on
line 6 of the file
are pushed into a new row of the data.frame. In other words, the extra columns
on line 6
