Finally, I recompiled R (upgrading to 2.12) and I am still getting the same error. I appreciate insights that anyone has as to what could be going on.

...Is it an inconvenience to require that all data use a period as decimal point? (i.e., 3.14159 rather than 3,14159). We're trying to make our program as foolproof as possible, and would prefer not to give users a chance to have commas as both decimal points and field delimiters.

...help files seems to indicate that R ought to manage its memory itself. I know I have enough memory since stata handles these files perfectly well. I have a mac running OS 10.3 and am running RAqua 1.8.1. Is there anything I can do to make it deal with these files successfully?

...ut off where a window had been. Also, when it computes something, the window will often decide to move itself over for no apparent reason, so it moves one button at a time, very slowly --- this doesn't happen under linux or Mac.

How does one put quotes within quotes, if it's possible? I've tried replacing one set of the quotes by single quotes.

I hope someone here knows the answer to this since it will save me from delving deep into documentation. Based on 22 pairs of vectors, I have noticed that tetrachoric correlation coefficients in stata are almost uniformly higher than those in R, sometimes dramatically so (TCC=.61 in stata, .51 in R; .51 in stata, .39 in R). Stata's estimate is higher than R's in 20 out of 22

The R documentation for some of the foreign package's functions says that the set of variable labels becomes attributes in the resulting data frame. Thus, e.g., 5="strongly agree", 4="agree", etc. I'm happy that the labels are being passed, but unfortunately, when R summarizes the data, it will list it only as categories, and doesn't deal with the

Hi, i'm newbie for this, but it's very interesting, but how i have to interpret the results if i get i.e. this results ? Is it correct - if the "Ratio of effect sd" is positiv than the Numerator effects are bigger , and the negative case vice-versa ? Ratio of effect standard deviations: 0.954 Log(sd ratio): -0.047 (se 0.828) Approximate 95% confidence

I'm trying to learn Samba on a Linux 7.0 box. I've just installed Samba 2.0.7. I've been able to run all the tests in DIAGNOSIS.TXT, manually edit the smb.conf file, and I can even see some folders on the Samba server from a Windows 98 machine on my LAN. But I am unable to run SWAT on the Samba Server (or from any other computer on my LAN). Every time I enter http://localhost:901/
