[R] Forcing the intercept
Dear R-users: I am doing multiple regressions using the lm function and would like to force the intercept to be equal to a specific value (such as 4.3). I was able to find out how to force it through the origin but this does not work for other values. I am also interested in forcing the regression parameters obtained from one regression in another regression with a subset of the data. Are either of these possible in R? I have been searching the help guide for hours and have been unsuccessful. Many thanks, Heather __ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
[R] Using MAANOVA functions
Dear R-users: I am using the package MAANOVA to analyze microarray data and have encountered problems when trying to plot data. I have tried emailing a MAANOVA discussion group, as well as the author of the package, and have not yet received a response so I am hoping that someone on this listserv can be of assistance. There are several functions in MAANOVA (riplot, resiplot) which call the plot function. For some unknown reason, when I use these functions, it appears that xlim has not been specified and I get an error (see below). However, when reading the code for each function, a command for how to calculate xlim has been specified but for some reason it does not get done. Does anyone have experience using MAANOVA commands and is willing to help? Here is an example of the error I get. It is identical also for the resiplot command: riplot(spore) Error in plot.window(xlim, ylim, log, asp, ...) : need finite 'xlim' values Many thanks, Heather -- __ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
[R] Citation
Does anyone know R is to be cited in a publication? I've looked everywhere on the website and cannot find this.

[R] Importing module into R library
Hello, I am basically familiar with R and am trying to import a module that someone else has written. I know that it must go into the R library but even after I place the file there R doesn't recognize it. The module is maanova, available from the Churchill lab group for analysis of microarray data, if anyone is familiar with it. Any ideas/help?
