Dear All, Currently, I am translating Matlab code to R. I met difficulties to translate such Matlab codes into R: fprintf(fid,(' SPLITTING RESULTS ')); fprintf(fid,(' \n')); fprintf(fid,' Data base to analyze is a matrix %4i x %2i ',[n m]); fprintf(fid,' \n'); fprintf(fid,' h is %2i',h); fprintf(fid,' \n'); fprintf(fid,' group=0

Hi All, I am doing econometric modeling of panel data (fixed effects). We currently use Eviews to do this, but I have discovered a bug in Eviews 7 and am exploring the use of R to build panel data models / longitudinal data models. I looked at the plm package but do not see how I can incorporate AR terms in the model using the plm package. I have an Eviews model with two AR terms, AR(1) and

Hi, I've built a function to generate plots and would like to be able pass in column names as a parameter. Here's a boiled down version of what I have right now: pmts <- data.frame(date=c(1,2,3), all=c(5,6,7),maj=c(4,5,6),ind=c(3,4,5)) perc.mktshare <- function(df){ range1 <- floor(min(with(df, 100*ind/all))) range2 <- ceiling(max(with(df, 100*ind/all)))

I started to check what I thought I knew with autocovariance and it doesn’t jive with the the calculations given by ‘R’. I was wondering if there is some scaling or something that I am not aware of.

We have a variable that we use to label bars in barplot() and to condition on in xyplot(). Since the labels can be quite long, we use strwrap() on-the-fly to split the strings into several "lines" separated by "\n". With barplot, this works nicely using text(), but with xyplot() it doesn't. In the latter, the labels appear to be "double-spaced" compared to the

When playing around fitting unconditional growth models using R and MlwiN today, I produced two different sets of estimates that I can't reconcile and wondered if anyone here has an idea: The data is two-level repeated measures data with measures nested within child. There are two measures per child. I've fit an unconditional growth model as in Singer and Willet (2003) that allows for
