UseRs, I tried to install the MatchIt package on Ubuntu 7.04. When loading required dependencies I got the following error message: Error in dyn.load(x, as.logical(local), as.logical(now)) : unable to load shared library '/usr/local/lib/R/site-library/optmatch/libs/optmatch.so': /usr/local/lib/R/site-library/optmatch/libs/optmatch.so: cannot map zero-fill pages: Cannot allocate memory Error: package/namespace load failed for 'optmatch' optmatch.so appears to be where R is looking for it so I don't know what has gone wrong. Have I mis...

Hello , My optmatch package is loaded on R and otherwise running fine. I get an error after lcds successfully completes a logistic regression and I then try to obtain a propensity score: pdist <- pscore.dist(lcds) Error: could not find function "pscore.dist" Does anyone know if pscore.dist is part...

...ice que no puede abrir un directorio y no realiza la instalación. También he probado a hacerlo directamente desde el repositorio, y me da el mismo error. Mi problema principal es que necesito instalar el paquete ?MatchIt? y cuando empieza la instalación me dice que no puede instalar la dependencia ?optmatch? porque en el repositorio hay una versión posterior a la que necesita. ¿Alguien me puede ayudar? Muchas gracias Pepe Martín

Good afternoon Running R2.10.0 on Windows I have a data frame that includes (among much else) a factor (In_2006) and a continuous variable (math_3_4). I would like to find the 2 cases for In_2006 = 0 that are closest to each case where In_2006 = 1. My data looks like In_2006 math_3_4 0 55.1 1 51.6 1 18.1 1 26.6 1 14.1

Hi, Is there any R implementation of the well-known algorithm from the Operations Research literature, the Ford-Fulkerson algorithm of maximum flow in networks with capacities. Thanks. [[alternative HTML version deleted]]

May I ask a clinical question? For a trial, we have a treatment group of small size, say 30 patients. We want to selectmatching control patients from a bigger group (100 patients) in terms of several clinical variables, such as age, tumor stage etc. This practice is to select the closest matching set of control cases. I wonder if R has any routine or package that can help with this problem.

The right way to handle this is only to make these packages as "suggests" rather than "depends" and then install them if needed, as you do correctly with optmatch. Note that Writing R Extensions says: "Packages that need to be attached to successfully load the package using library(pkgname) must be listed in the Depends field." Although this is not directlty on point, my interpretation is that you need a "good reason" to list a package...

...tion that is incompatible with the GPL), but states an explicit dependency on the MASS package (which is not a "base" package and released under the GPL). Furthermore, several packages also prohibit commercial use, but list an explicit dependency on the methods package (e.g. gpclib, isa2, optmatch). As all of these packages are on CRAN, and at least one author is also a core R contributor (Duncan Murdoch for gpclib), I assume that the CRAN maintainers and/or the R Foundation do not consider these packages to violate the GPL, and therefore also do not agree with the FSF interpretation of the...
