Dear all, Thanks to those of you who have replied, the majority of the comments pointed out that the error caused by scan may originate from another function, and closer inspection of the output from traceback() reveals that it is in fact the read.table function where the error is originating from the full output of which I have included below. The error msg I recieve is Error in

Hello, rsync.h is always including the syslog.h file, even though it is only used when the LOG_DAEMON macro is defined. Could someone change it to be as follows: #ifdef LOG_DAEMON #include <syslog.h> #endif OpenVMS currently does not have a syslog facility, so it does not have a syslog.h. Thank you, -John wb8tyw@qsl.net Personal Opinion Only

Hello to everyone, I have 2 problems and would be very pleased if anyone can help me: 1) When I use the package "systemfit" for SUR regressions, I get two different variance-covariance matrices when I firstly do the SUR regression ("The covariance matrix of the residuals used for estimation") and secondly do the OLS regressions. In the manual for "systemfit" on page

Hi, I have a vector, which contains both strings and numbers, e.g. > foo <- c("str1",1234,"str2",0.9876) I want to know if a distinct element of the vector is a string or a number and took "is.numeric", but > is.numeric(foo[2]) [1] FALSE because R treats the numbers in a mixed vectors as strings: > foo [1] "str1" "1234"

Compaq C 6.5 OpenVMS Alpha 7.3 The config.h.in template file is missing the line: #undef HAVE_INET_NTOP This caused the resulting CONFIG.H on OpenVMS to not test for the existance of the inet_ntop() routine in it's system tables. This configure bug exposed that the prototype in inet_ntop() in RSYNC.H does not match the one in the Compaq C header files. This stopped the build. I am

Hi, I have a dataframe (say myData) and want to get a list (say myList) that contains a matrix for each row of the dataframe myData. These matrices are calculated based on the corresponding row of myData. Using a for()-loop to do this is very slow. Thus, I tried to use apply(). However, afaik apply() does only return a list if the matrices have different dimensions, while my matrices have

Hi, I'm no phone guy but I've been having quite a bit of fun messing with Asterisk. I just unwrapped my new Wildcard TDM400P (TDM40B) which is the new 4 port FXS PCI card. It has 4 RJ45 connectors and I'd like to hookup 4 regular phones which are RJ11. If I crip RJ45 connectors to the phone cords do I simple use the center two pins (pins 4 and 5)? Thanks, Randy Smith Tiger

Dear R Users: The functions of our "micEcon" package [1,2] can be subdivided into three categories: - microeconomic demand and firm models - sample selection models (mainly selection()) - routines for (likelihood) maximisation (e.g. maxLik(), maxNR(), maxBHHH()) (mainly used for ML estimation of sample selection models) Although sample selection models are often used in

Hi, I was really happy when I saw that in R version 2.3.0 "R CMD check" works for packages whose package name is different from the directory name in which it is located (see http://cran.r-project.org/src/base/NEWS). Now, I can have branches of my packages in directories like "[...]/branches/<version number>/", while I had to use "[...]/branches/<version
