Hi all, I have a series of cateogiral variables that look just like this: welfare=sample(c("less", "same", "more"), 1000, replace=TRUE) education=sample(c("less", "same", "more"), 1000, replace=TRUE) defence=sample(c("less", "same", "more"), 1000, replace=TRUE) egp=sample(c("salariat",

Dear R-members, Suppose I have a vector with the following strings: V = c("Welfare_Group_1024", "Welfare_Group_1536", "Welfare_Group_160") I want to 'automatically generate a nice y-axis label for this data. A good candidate is something close to "Welfare Group". Is there an easy way to compute something close to the greatest common

Can anyone tell me how I can supply more than one graph to plotCI (gplots) at once? Below is what I tried, also with rbind instead of cbind. What is the way to do this (in general, I think)? Problem is that lines of 1-st and 2-nd series are mixed, while they have nothing to do with each other. I also tried calling plotCI with argument add=TRUE, which didn't seem to work (that is actually

Hi Y'all, I am using the text mining package (tm). I am trying to filter out all of the words in a Term Document Matrix that are not in a list of words that I am interested in. I am using the following code: z<-tm_intersect(txt.dtm, c("communications", "safety", "climate", "blood", "surface", "cleanliness",

Hello all. I am doing one part of an evaluation of a mandatory welfare-to-work programme in the UK. As with all evaluations, the problem is to determine what would have happened if the initiative had not taken place. In our case, we have a number of pilot areas and no possibility of random assignment. Therefore we have been given control areas. My problem is to select for survey individuals in

I came across this notice of an upcoming webinar. The issues identified in the first paragraph below seem to me exactly those that the R project is designed to address. The claim that "most research software is barely fit for purpose compared to equivalent systems in the commercial world" seems to me not quite accurate! Comments!

Hello Ivo: One more from me and I suppose a retort by you and that's it ... no flame war please. Let's see if we can keep this discussion objective. I've had enough life experience to have seen and heard the mistakes you've made many times. Point by point: * This is a tech list that I joined a number of years ago because of a serious intent to use the Speex product in my

Welcome to "Ghetto" America! …...Yes, you heard me; I said "Ghetto" America! What is "Ghetto" America, I'm glad you asked. Before I go on please be warned, this explanation may not sit well with many of you, however it is no less true! "Ghetto" America is a society of individuals comprised primarily of African Americans who represent the

The disaster in the Gulf coast and the less than optimal initial response suggests to me that citizens must shoulder more responsibility for emergency management. Communications loss must have played a large role in the failures that occurred. I can't help but wonder if there are fewer ham radio operators today and that if there were more, maybe they could make a difference in future

I need to review a logfile with Sed and cut out all the lines that start with a certain word, problem is this word begins after some amount of whitespace and unless I search for whitespace at the beginning followed by "word" I may encounter "word" somewhere legitimately hence why I don't just search for "word" only... Anyone know how to make sed accomplish this?

Hello, I've just carried out my first good-looking model using glmmPQL, and the output makes perfect sense in terms of how it fits with our hypothesis and the graphical representation of the data. However, please could you clarify whether my degrees of freedom are appropriate? I had 106 subjects, each of them was observed about 9 times, creating 882 data points. The subjects were in 3
