..., and it seems to invoke dqrls . is this the recommended way, or is there a higher-level more stable matrix inversion routine that I could use? help is, as always, appreciated.

Hi, I am moving from Windows XP to Ubuntu 6.10 and installed R 2.4.0. When I run eg plot.lm (things work fine with plot.default - eg plot(rnorm(30),rnorm(30))) plot(lmobject) I can get the first plot and then this message: Hit <Return> to see next plot: Error in text.default(x, y, labels.id[ind],cex=cex, xpd=TRUE, : could not find any X11 fonts Check that the Font Path is correct I have googled through the R-help list and it seems that such troubles alrea...

Hi Please let me know if we can store the linear model object in the data base and retrive the object and output from them Data<- read.csv("C:/FE and RE.csv") Formula="Y~X2+X3+X4 lmobject = lm(formula=Formula,data=Data) can i store the lm object in the database and and is it possible to retrive it and get the summary information -- View this message in context: http://r.789695.n4.nabble.com/Storing-the-linear-model-object-tp4121944p4121944.html Sent from the R help mailing list a...

...y requirements. 3) The StatDataML package in R provides the creation of xml files of R objects. Maybe I can use these XML files as encapsulators of R object data and pass it on to FLEX. 4) Since R has interfaces that connect to most SQL database servers, I can convert results of lm objects (summary(lmobject)) to data frames and push them into the SQL database. FLEX can then read the table and extract the relevant fields for output. I am aware that I not a computer programmer which is why I may not be making a whole lot of sense in describing the above scenarios, but I am trying to gain as much inform...

Dear R experts, I am posting this question on behalf of a Japanese R user who wants to know how to change the siginificant codes default. As you know, R's default significant codes are: Signif. codes: 0 `***' 0.001 `**' 0.01 `*' 0.05 `.' 0.1 ` ' 1 But he says that it is usual in economics to give codes such as `***' for 0.01, `**' for 0.05 and `*' for

I'm using R for Mac OS X Aqua GUI version 2.0 When using plot() with a linear model object, the plot of the LSR line does not appear. I get the residual plots, the Normal Q-Q plots and Cook's Differnce plot, just not the first plot with the fitted line. I just get an empty Quartz window, with no graph displayed. I've even tried to use plot.lm() and plotting a glm object, but I get the

I am having problem using the step function for a linear regression model. I've created an initial model containing only the intercept. Then using the step function, I've selected three variables to be considered for the model. > x0.lm<- lm(MEDV~1, data = x) > > anova(x0.lm) Analysis of Variance Table Response: MEDV Df Sum Sq Mean Sq F value Pr(>F)
