...e 2 datasets on top of one another. (I have manually checked to make sure that there are common ID numbers in both datasets and there are.) I assume that I'm getting this stacked data because by not specifying a by variable, R is trying to match on all variables in the datasets and there are no exaxt matches across all the variables? I've also tried to strip any white space that may be causing problems in the file. (Not sure if this is a good or bad idea.) > newdata <- read.table("olddata.csv", header = TRUE, strip.white = TRUE, sep=",") I'd be r...

Hi all, I was trying garchFIt() of fSeries to fit volatility of monthly log returns of S&P500. I tried residuals of normal, student t, skew normal, skew t. But all innovations except normal got exaxtly same coefficients, even if I changed their parameters of skew and shape. Is this correct for the data or something wrong? I am attaching the code, thank you. Muster #GARCH analysis of monthly return rm(list=ls(all=TRUE)) sp500 <- read.csv('s&p_m.csv', header=TRUE) sp500 <- sp...

I (still) use RCS, and not CVS, for my own projects. R CMD check does not like the 0444 file permissions on files check into RCS. I conjecture that this stems from desire to have the installed files in a state in which they can be edited, but I might be off base ... In case my conjecture holds, would it be possible to relax the restriction during R CMD check, but then install the files as 0644
