...es of linear models where each term is dropped in turn. I can get the RSS from drop1(), and the r.squared from summary() for a given model, but don't know how to use the result of drop1() to get the r.squared for each model with one term dropped. Working example: library(vcd) # for Baseball library(car) # for vif/recode data(Baseball) # sal87 appears as a factor because missing is coded as '.' rather than NA Baseball$sal87 <- as.numeric(recode(Baseball$sal87, "'.'=NA")) Baseball$logsal <- log(Baseball$sal87) base.mod <- lm(logsal ~ years+at...

I?m trying to pull data from one table (batting) in the Lahman Baseball database. Notice X2B for doubles and X3B for triples ? fourth and fifth from the right. The dbGetQuery function runs fine when I leave there two out but I get error messages (in red) when I include 2B/3B or X2B/X3B. Can anyone give me some direction?

Hi everybody, I''ve started to learn Ruby on Rails with the two books, of course I''m experimenting outside the examples in the book and walking against some things I didn''t learn yet. so here''s the question: Is it possible to access one model from within another? Actually I have a Many to Many relationship between tables and I''m trying to realize

How do the R "powers that be" handle packages that are orphaned from CRAN? Recently, I was looking for a function either part of the base functionality or an add-on package that mimicked the "poly" functionality from Octave (http://n4.nabble.com/Re-R-function-that-duplicates-Octave-s-poly-function-td901174.html) Based on that post a helpful R user strongly encouraged me

Anyway, I setup the VPN Concentrator to auth off of the samba box, and when I test it with the test option, and it works, but when I try to auth a pptp tunnel, it fails saying the password is wrong. Any ideas? My vote is for the stupid concentrator to meet some thermite or a metal baseball batt. -------------- next part -------------- A non-text attachment was scrubbed...

Is it possible to trace Samba authenticated user? That is, after a user has been authenticated versus a Samba acting as PDC, is it possible to know if such user is still connected to the Microsoft network or they have been disconnected? What I would like to do is to use Samba as authentication server in order to grant the access to other services (for example Internet navigation through a proxy)

Dear List Members, I am in the process of designing a study examining pay and performance in Major League Baseball across several seasons, and before I get too deeply into it, I'd like to ask whether the group members think that performance across seasons is independent, or if it needs to be treated like a time-series variable so that lack of independence can be controlled. Any ideas or considerations t...

Dear all, I generated a Correlograms and used the panel.ellipse (confidence ellipse and smoothed line) option. Is there a way to get instead of the smoothed line the linear regression?

I am using R to plot baseball spray charts from play-by-play data. I have used the following command to plot the diamond: plot (0:250, -250:0, type="n", bg="white") lines(c(125,150,125,100,125),c(-210,-180,-150,-180,-210), col=c("black")) I have also plotted different hit locations using command...

...quot;id" represents repeated observations over "time" and I want to scale the "slope" variable. The "out" variable shows the output I want. My for..loop does the job but is probably very slow versus other methods. ddply seems ideal, but despite playing with the baseball examples quite a bit I can't figure out how to get it to work with my sample dataset. TIA for any help, Roger Here is the sample code: dat <- data.frame(id=rep(letters[1:5],3), time=c(rep(1,5),rep(2,5),rep(3,5)), slope=1:15) dat for (i in 1:3) { mat <- dat[dat$time==i, ] out...

Greetings! I'm have a hard time working with some data I imported from a baseball database. Several of the database columns have numbers in them (2B, 3B), and when I try to use these vectors from the data frame, I get syntax errors, probably because it's interpreting the name as a number: > show(batting2005) playerID yearID stint teamID lgID G AB R H 2B 3B HR...
