Hi there, I just saw your question on the help list and tough you could help me with some start-up info.... I just downloaded the R project software to try running SEM analysis and I also downloaded the SEM package. But it just sits there on the desktop and R does not know where it is...I can¹t figure out how to organize the files...When I type ?sem in R it says object sem not found...I can¹t seem to find help on the web on how to set-up the packages.... Well, thanks in advance __________________ Patrick Bedard Ph.D. Dept. of Neuroscience Brown University [[alternative HTML version deleted]]
Dear Patrick, It's hard to know how to help since you provide very little specific information. For example, what OS are you using -- Windows, Mac OS, Linux? Packages such as sem have to be installed before they are usable, and even then ?sem won't provide you with information before the package is loaded via library(sem). You might start by reading the Introduction to R manual that comes with R. Among other things, it explains how to install packages. Under Windows, for example, the easiest way to proceed if you have an active Internet connection is via the "Packages -> Install package(s)" menu in the R console. I hope this helps, John On Wed, 28 Jun 2006 15:53:55 -0400 Patrick Bedard <Patrick_Bedard at brown.edu> wrote:> Hi there, > > I just saw your question on the help list and tough you could help me > with > some start-up info.... > > I just downloaded the R project software to try running SEM analysis > and I > also downloaded the SEM package.

For me on either WinXP Pro or Linux (SuSE10.0), the easient way to install a package is to start up R and then type > install.packages() This will pop up window to select a package repository. You will then be given a list of packages from which to select. Selected packages will be download and installed. (You can also install the file you already downloaded - see the docs) Then to use the installed package you need to load it with the command > library(sem) You will then be able to use the functions from the sem package. There is lots of documentation in the manuals included with the R software. You should read them along with the FAQ. These can all be found with your R installation or you can read them on your nearest CRAN mirror. Hope this is helpful, Dan Daniel J.
