Re: [R] For two vectors, how to plot bin-to-bin histogram comparision in R?

Of course the OP failed to note that no pictures can come through... But anyway, Do not do this! It can be highly misleading (due to arbitrariness of binning). See ?qqplot for a much better way to compare distributions.(alas, rarely used except by statisticians) -- Bert Bert Gunter Ge

[R] Aligning names with variable values

Many of the statistics reported don't make sense with only two items--for example the alpha if an item is dropped makes no sense because dropping an item leaves only one remaining. Best, Ista On Fri, Feb 14, 2014 at 5:24 PM, Johannes Moser wrote: > Dear R-help, > > I try to estimate alpha for a

[R] Random Forest, Variable Mismatch

Dear All, I am a bit puzzled. I am developing a random forest model. The data is large and it involves hundred of predictors, but the code I have written is relatively simple. After training my random forest model, I apply it on some new data set to carry out some prediction, as you can see be

[R] Subsetting a named list of parameters in mle

[R] Data Upload

Hi, I have some question of using "R". As we know "R" is connecting to CRAN Mirror for packages update, I am afraid that the data we import into "R" will be uploaded to somewhere i.e. server. Could you confirm that "R" is purely run on the local machine without connecting to any server for data

Re: [R] Subsetting a named list of parameters in mle

fit is initialized as a vector of integers. How can you assign an mle fit to an element of an integer vector? Initialize fit as a list, use lapply, or whatever. Have you read An Intro to R (ships with R) or other R (e.g. web) tutorial? This looks like the sort of basic misunderstanding that one wh
