Hi, I''m trying some RJS to update a series of list boxes in which the user selects a state, and the following list gets updated with a list of counties, and the same for the next list of areas. My code works perfectly (albeit a bit slow) on Firefox, but on Internet Explorer it clears the list box (instead of filling it) and Netscape shows all the counties cramped together on one

Hi! I thought I understood Ferret''s query scoring and how to tweak results using boost values. What I currently experience however, leaves me completely baffled. Perhaps someone can shed some light on the scoring algorithm, because asking Ferret to "explain" the score for a particular document isn''t as informative as I thought. Actually, it confuses me even

Hi, I have a scatter plot of the variables GNI and Lifeexp (Gross National Income and Life Expectancy, both metric). So I plotted them and I want to add a regression line and a lowess line. I use lowess and not loess because I have missing values. My code: plot(GNI,Lifeexp) abline(lm(Lifeexp~GNI), col="red") y.loess<-loess(Lifeexp~GNI,na. action = na.exclude)

Hi All, This is surely an easy question but somehow I am not being able to get it. I am using R 2.13.2 and have a data set where variable names like this appear: pci1990, pci1991, ... , pci2009. "pci1990" has data on per capita income for 1990, "pci1991" has data on per capita income for 1991, and so on. I would like to create the logarithm of per capita for each of the

Hi, I want to make model selection with regsubsets. My code is: a<-regsubsets(Gesamt ~ CommunistSocialist + CountrySize + GNI + Lifeexp + Schoolyears + ExpMilitary + Mortality + PopPoverty + PopTotal + ExpEdu + ExpHealth, data=olympiadaten, nbest=2) summary(a) plot(a,scale="adjr2") (output attached) The problem is now, that I want to fit the best model again "manually"

Hi there, I''m still trying to wrap my head around when to use a stub and a mock. If I understand this right, I should be using a ''mock'' when imitating an object, but not its behavior. I should be using a stub when I want to imitate the behavior of an object. Does that sound about right? With that said, I''m struggling a little trying to spec out this instance

Dear all, I'm trying to remove some text after the period (a decimal point) in the data frame 'hi', below. This is one step in formatting a table. So I would like e.g. "2.0" to become "2" and "5.3" to be "5.3", where the variable digordered contains the number of digits after the decimal that I would like to display, in the same order in which

Hi all. We have a bunch of RHEL servers running Puppet. They are also connected to our Red Hat Satellite server. Currently we don''t have any master documentation system that stores all relevant information (i.e. type of server, hardware info, linux configuration, etc) about the servers. So what I''d like to do is implement some sort of system that can hold all this information.

I'm trying to call BUGS from R. But it's not working. R freezes up and BUGS gives me a strange output in the log. Just to know, BUGS is registered. The modified date on the keys file is today (Dec. 9th). It should be fully registered so that I can use it fully. And, the BUGS model is syntactically correct. Any suggestions would be very helpful. Here is my BUGS model: model {

Hello everyone, I was asked to repost this again, sorry for any inconvenience. I'm looking replacement for ddply function from plyr package. Function allows to apply function by category stored in any column/columns. Regular loops or lapplys slow down greatly because my unique combination count exceeds 9000. Is there any available solution which allow me to apply function by category?
