[R] 95% confidence intercal with glm

Hi I had to use a glm instead of my basic lm on some data due to unconstant variance. now, when I plot the model over the data, how can I easily get the 95% confidence interval that sormally coming from: > yv <- predict(modelVar,list(aveLength=xv),int="c") > matlines(x

Re: [R] A problem with plotting a long expression in ylab ?

Hi Barry, Sorry for not being clear. "Not work" == "Doesn't add the text to the ylab" My initial example was intended with no line breaks. Here it is again with variations: plot(1) title(ylab = expression(paste("test ln

[R] A problem with plotting a long expression in ylab ?

Hello, It seems that there is a problem when plotting an expression in the ylab of a plot in case it is too long. Example: plot(1) title(ylab = "test looong ") # work plot(1) title(ylab = expression(paste("test (% of 360" *d

Re: [R] Regular expressions: offsets of groups

What Titus wants to do is akin to retrieving capturing groups from a Matcher object in Java. I also thought there must be an existing, elegant solution to this some time ago and searched for it, including looking at the sources (albeit with not much expertise) but came up blank. I also looked at t

Re: [R] hcluster with linkage median

Thank you Peter for your help. I had tried hclust before but I made the mistake of using the D matrix above instead of a dist object. Hence library(flashClust) d <- as.dist(D) # Clustering using hclust hc <- hclust(d, method = "median",members=NULL) # Clustering using flashClust fc

Re: [R] max length of a factor variable

Thanks I eventually tracked down the problem to something unrelated to this question (one out of the millions of character strings happened to be "NA" by chance, which of course was parsed as a missing value, breaking the code a long way downstream.) Richard On 28/09/2010 04:01, Michael
