I have a few functions, such as screenWidth() and screenHeight(), which I have been able to implement for a Unix/Linux environment, but not for Windows. (Does anyone know how to find the screen dimensions in Windows?) The Writing R Extensions manual tells me how to include platform-specific sections in documentation, and even how to have platform-specific help files. But it doesn't say

Good Morning, I am trying to create a new column of character strings based on the first two letters in a string in another column. I believe that I need to use some combination of ifelse and grep but I am not totally sure how to combine them. I am not totally sure why the command below isn't working. Obviously it isn't finding anything that matches my criteria but I am not sure why. Any

One hassle I could do without is the necessity of writing C wrapper functions like this: void fameInit(int *status){ cfmini(status); return; } when I want to call a library function (cfmini, in this case) that takes an int argument. The .C interface only lets me pass a pointer to an int, rather than the int itself. Is there any chanch that .C could be enhanced to allow passing arguments by

I'm in the process of learning Samba and evaluating it as a possible replacement for Windows NT servers in our office next year. I have set up a small test network comprised of one NT 4 (SP6a) Workstation, one Windows 2000 Pro (SP3) and one Fedora Core 3 running samba 3.0.11 as a PDC. I'm using LDAP as the passdb backend with smbldap-tools 0.8.7-1. The Windows 2000 Pro machine can join the

I think one of the more interesting phenomena in the world of wine that has arisen in the past five years is the emergence of a group known as the American Association of Wine Economists. I must admit, when I first saw the announcement of their existence, I assumed it was just some economists having a good time and looking for an excuse to drink some more wine.http://chloehandbagsspring2011.com

Cologne, 10.12.00 Dear Sir, Dear Madam, We are concerned about the possibility that the European Commission might introduce software patenting into the European Community because we think this will harm our profession. We make our living on data management and statistical analyses. Modern statistics crucially depends on algorithms [cf. Venables, W. N., & Ripley, B. D. (1999). Modern applied

Hi Everyone, I am uncertain that I am writing the contrast statements correctly. Basically, I'm unsure when to use a -1 and a 1 when writing the contrasts. Specifically I am interested in comparing the slopes between different temperature regimes. Temperature is therefore a factor. Time and percent are numerical. Using the gmodels package I made the following model:

Hi, The department of economics at our university (Budapest) is planning a course on numerical methods in economics. They are trying to decide which software to use for that, and I would like to advocate R. The other alternative is Matlab. I have found comparisons in terms of computational time for matrix algebra, but I don't think that is relevant: the bottleneck for economists is usually

I have spent hours on R in Windows 7. Just installed 2 days ago so the R package should be current. Currently I am using the RGui (64-bit) for Windows. I can not read an Excel file into R from my computer. Have hours on this. Completely crazy!! I have the XLConnect package loaded. I think it is loaded because when I enter: > loadedNamespaces() [1] "base"

Hi, I did not find any web page about using R in economics and econometrics so far. However, this does not mean that there is none (searching with google for "R" and "economics" gives many pages about economics and a name like Firstname R. Lastname on it ;-)). Does anybody in the list does know such a web page? If not, I will be happy if you, Ajay, could build and

Hello all, I would like to rigorously test whether observations in my dataset are outliers. I guess all the main tests in R (Grubbs) impose the assumption of normality. My data is surely not normal, so I would like to use something else. As far as I can tell from wikipedia, Peirce's criterion is just that. The data I am interested in testing is: 1) Continuous on the unit interval 2)
