Re: [R] NADA Data Frame Format: Wide or Long?

Hi Rich, So what you're faced with is that the cenros() function has no built-in methods for grouping or subsetting -- unlike some other R methods, especially those that work with the lattice package, or the many modeling functions like lm() that have a subset argument or employ a conditioning

[R] differences between survival models between STATA and R

Dear Community, I have been using two types of survival programs to analyse a data set. The first one is an R function called aftreg. The second one an STATA function called streg. Both of them include the same analyisis with a weibull distribution. Yet, results are very different. Shouldn't

Re: [R] Plotting the probability curve from a logit model with 10 predictors

Ok, so let's say I have a logit equation outlined as Y= 2.5 + 3X1 + 2.3X2 + 4X3 + 3.6X4 + 2.2X5 So a one unit increase in X2 is associated with a 2.3 increase in Y, regardless of what the other predictor values are. So I guess instead of trying to plot of curve with all the predictors accounted

Re: [R] Mann-Whitney by group

Hi David, Thank you for the insight: I could have sworn I added a picture of the data, but providing the actual data is worlds easier to deal with, I'm sure. I've never used dput(), so I entered it using the dataframe in question as the object, and I've pasted the results below. Essentially, I

[R] How to compare stacked histograms/datasets

Re: [R] Is R BOOT package available for 2.15.1 version for Mac OS?

David, thanks for your helpful response. Now i figured out that I do have boot command and do not need to install any additional packages. With regards t R GUI, I guess I would like to use it, but I could not figure out how to install it. For now I downloaded R-2.15.1.pkg file, which I could

Hi J, You have not provided nearly enough information for us to evaluate whether the results should be similar. You are talking about two completely different packages, with no information on your data, only a small amount of information about your model (the same analysis) but clearly the

Re: [R] How to intall car package on linux

Install.packages needs a quoted argument -- the error message suggests that its looking for a variable named `car` and not finding it -- in fact, most functions taking package names do, but library() allows some trickery, which is convenient, but occasionally leads to mishaps like this.
