Hi
I like to use logical values directly in computations if possible.
yourData[,10] - yourData[,9]/(yourData[,8]+(yourData[,8]==0))
Logical values are automagicaly considered FALSE=0 and TRUE=1 and can be used
in computations. If you really want to change 0 to 1 in column 8 you can use
Hi lattice users,
I would like to add 5-year moving averages to my double y-plot. I have three
factors needs to be plotted with moving averages in the same plot. One of these
reads off y-axis 1 and two from y-axis 2. I have tried to use the rollmean
function from the zoo-packages, but I fail

I am trying to do a simple thing of calculating the absolute difference
between 2 previous values. Since my original data consists of 30 rows,

Thanks but that doesn't work: R cannot load a simple external library
even if the full path to the directory is specified in the LD_LIBRARY_PATH.
I posted a minimal example on gist.github:

Thank you very much!
The idea was to use it with an external reference and kind of to write an
constructor
for an object which points at this external reference and behaves like an R
object.
So it would be the same as if I do just

Hi Elizabeth,
In confirmatory factor analysis with multiple groups, the reason one needs
to estimate the models simultaneously is that, typically, one is interested
in applying constraints (e.g., forcing all or some of the factor loadings
to be equal across groups). In exploratory factor

Hi,
The area of statistics you're looking for is called geostatistics.
There are many R packages to conduct such analyses. See the Spatial
task view for some good starting points:

You'll need to do some homework to understand the various options

Hi Anna
Not sure what you want exactly as I do not use themes.
Here is one way to get your averages and points
# combine averages into mydata
mydata$mavg -
c(rep(NA,4), madfStuff1[,3],
rep(NA,4), subset(madfStuff2_3, Type== stuff2,3, drop = T),
rep(NA,4), subset(madfStuff2_3, Type==
An utterly perfect example of why one shouldn't send HTML mail to this list.

Thank you very much Peter, Bill and Petr for some great and quite
elegant solutions. There is a lot I can learn from these.
Yes to your question Bill about the raw numbers, they are counts
and they can not be negatives. The data is RNA Sequencing data where

I believe the interpp() function from the akima package will do what you
want.

Above what David said, there is chance that you do not need cycle for your

From what you describe about your csv files there seems to be some mismatch in

¿Has podido sobre tus dos discursos utilizar la misma lógica?
