Help with lm and multiple linear regression?
Hello, I'm new to R, but I've read the intro to R and successfully connected it to an instance of mysql. I'm trying to perform multiple linear regression, but I'm having trouble using the lm function. To start, I have read in a simply y matrix of values(dependent variable) and x matrix of independent variables. It says both are data frames, but lm is giving me an error that my

S4 - inheritance changed by order of setClassUnion and setAs()
Dear colleagues, there is a behaviour with S4 (virtual) classes that I find very hard to understand: Depending on the position of setAs(), the tree of inheritance changes. This is my baseline example that defines the classes "grandma", "mother", "daughter" and a virtual class "mr_x". For a new instance if "daughter", "mr_x" is betweeen

S4 - inheritance changed by order of setClassUnion and setAs()
Andreas, As far as I can tell (/conjecture), this is because the list of classes a particular class inherits from directly is appended to as needed, and so the order that a class extends others isd refined by the order that those connections are defined. We can see this with two setClassUnion calls, rather than required setAs: > setClass("grandma", slots = c(a =

Matrix heatmap
I would like to organize my data as follows: I have a table that contains various data, and the numbers represent a level of similarity between these data, eg RF00013 has 100% similarity with the data RF00014. I would leave my table as a heatmap where darker colors represent higher similarity, and the lighter colors represent less level of similarity. I'm using version 2.11 of R. these

weird undocumented extensions such as s-BUSY
I've seen several examples that use extensions such as; s-BUSY s-NOANSWER etc... It's more or less evident what they do, but I've searched for some FORMAL documentation everywhere and have found nothing. Do they work for anything else than "s-"? (I think I've seen other examples, but can't find them now) Are they standard in any way? What are the allowed values

has and belongs to many different?
Is there such a thing? I am thinking of an application that has something like this: 1. person has many things - there is a ''persons'' table 2. the things he has are stored in a table that is something like this person_id, thing_table_name, thing_id For example, it may map to person1, books, 23 #Person 1 owns book 23 person1, books, 25 #Person 1 owns book 25

converting factors to dummy variables
Hi all - I'm trying to find a way to create dummy variables from factors in a regression. I have been using biglm along the lines of ff <- log(Price) ~ factor(Colour):factor(Store) + factor(DummyVar):factor(Colour):factor(Store) lm1 <- biglm(ff, data=my.dataset) but because there are lots of colours (>100) and lots of stores (>250), I run it to memory problems. Now, not every

Vista problem -- can't type commands at prompt
Hi All - I recently moved to Vista and reinstalled R. I am able to run R as I typically do (R.exe from the command prompt), and it can work well. However, if I switch windows to, say, firefox or excel or anything else, when I return to the R prompt it no longer works. I am able to use the up and down arrow keys to access previous commands, but no other key stroke has any impact. As long as I
