Hi,
I am using lm() for regression analysis of my data set. My regression

According to the help page sprintf will recycle its arguments:
The arguments (including fmt) are recycled if possible a whole number of
times to the length of the longest, and then the formatting is done in
parallel.

You need to provide us with some more information.
Please see if you can provide us with a simple example
of the problem code as is requested in the posting
guide.

All,
I recently made some changes to my package and ran R CMD check, but I
am getting a warning regarding my data sets.

for a factor are different than the alphabetized order returned a simple
list command, e.g., rpartModel$factor_name.
I was also wondering how best to mod
Look at the R help files for predict.Arima rather than using forecast
to forecast an ARIMA model. You might plot your data and the first
difference and you should be able to come to a conclusion about
stationarity. With your very small data set you need a very
parsimonious model. Knowledge about

Why not read the 'R Data Import/Export' manual? It ships with R, or can
be accessed from http://cran.r-project.org/manuals.html .

Hi,
Sorry for bothering your guys again. I am trying to use "par" to put 6
figures into 3 rows and 2 columns. My code is:
op <- par(mfrow = c(1, 2))
xyplot(x1+x2+x3 ~ y, data=resulta, type="l", pch=LETTERS[1:3], lty=c(1:3),
main="For k=3, theata1=1")
xyplot(x1+x2+x3 ~ y, data=resultb, type="l"
I am using MS Excel (Windos Operating system), how I
import/export data between MS_Excel and R.
