Hi,
I am a developer from Oracle. I wanted to create a png file out of png device
with a bit depth of 8. I am using R on linux. But I noticed that R
automatically switches between 8 and 24 bit depth. i tried a lot of things from
your grDevices package but unable to control the bitdepth.
which package from CRAN used for Big-Data analysis ?
is there any separate package for Big-Data analysis?
or for making reports Business intelligence

Probably because you post through Nabble which requires manual

write.table() should append just fine. write.csv() doesn't append I'm
told because there's no guarantee it matches the column headings of

It might help if you would bore us with at least one or two of the things
you have tried. It seems logical to read the file into a data frame using
read.table(). Then you can change it into any format you want:
Listname - read.table(text=key value
Key1 1
Key2 2
Key3 3, header=TRUE)
Listname
Sorry, I'm sure I'm not using the appropriate vocab here, which is
undoubtedly why I can't seem to find a fix to this (hopefully very
easy) problem.
Suppose you have a factor
abc - factor(c(2,2,3,4,7,7))
And you want to know what the number in the nth spot in that would be
abc[1]
[1] 2
Levels:
Hi Brigid,
as.numeric() extracts the index of the factor level, which is the way
R handles the likelihood that a factor is not actually numeric. Try:
as.numeric(as.character(abc[1]))
[1] 2
and see also ?factor particularly the section on the interpretation of a factor.

Hello,
Try instead
?levels
abc - factor(c(2,2,3,4,7,7))
as.numeric(levels(abc)[1])
Hope this helps,

Rui, that doesn't answer the question as I understood it:
Your suggestion returns the numeric value of the second value of the levels:
as.numeric(levels(abc)[2])
[1] 3
But I read the question as wanting the numeric value of the second
element of abc:
as.numeric(as.character(abc[2]))
[1] 2

HI,
May be you can use library(texreg):
library(plm)
#generating some data
x - rnorm(270)
y - rnorm(270)
t - rep(1:3,30)
i - rep(1:90, each=3)
data - data.frame(i,t,x,y)
fe - plm(y~x,data=data,model=within)
summary(fe)
library(texreg)
fe1-extract.plm(fe) #extract the plm object
I think David was saying the humor was unsuccessful (i.e., Christian
didn't get the joke), not that the code was.

Did not see a simple way to make it faster. However, this is a piece of
code which can be made to run much faster in C. See below.
I don't know if you are familiar with running c-code from R. If not, the
official documentation is in the R Extensions manual. However, this is

There are packages for big data analysis, which is best depends on
what you want to do. The High Performance Computing task view on CRAN
has a section on packages that deal with big data which gives some
more detail and may help you choose which package(s) to use.

Your original method would be the following function
f - function (x, y)
{
xy - cbind(x, y)
outside - function(z) {
!any(x z[1] y z[2])
}
j - apply(xy, 1, outside)
which(j)
}
and the following one quickly computes the same thing as the above
