I have a simple regression using lm(). If I just want to check the coefficient, I can use summary(lm())$coef; if I need the standard error, I can use summary(lm())$s, if I need the residuals, I can use summary(lm())$res. OK. How can I get the R-squares and Adjusted R-squares using $...? Is there a function, like objects(), that can show all the references for values? Thanks a lot! -- View this

Hello everyone, I have the following code that builds <option> into a <select>. buildModel() is called first, then setModel(). For some reason, I can''t get the length of the "model" options in setModel(), but can after they are built in buildModel(); function buildModel(originalRequest, json) { var model = $(''model''); //might need to

Hi, How would one go about determining if the slope terms from an analysis of covariance model are different from eachother? Based on the example from MASS: library(MASS) # parallel slope model l.para <- lm(Temp ~ Gas + Insul, data=whiteside) # multiple slope model l.mult <- lm(Temp ~ Insul/Gas -1, data=whiteside) # compare nested models: anova(l.para, l.mult) Analysis of Variance

Currently read.table is rather limited in its type conversion. The algorithm is 0) Read as character 1) Try to convert to numeric. If that works, quit 2) Convert to factor unless !as.is. I am thinking about adding more flexibility and more classes by the following two changes. A) Anticipating the arrival of classes for all R objects, add an argument say `colClasses' that allows the user to
