Re: [R] Is R good for not-professional-statistician, un-mathematical clinical researchers?

Jake, this is a great question. I have experience teaching R to forestry and natural resources graduate and undergraduate students. These students are amongst the least numerically comfortable students I've taught. I have found that the numerically comfortable among them leap into the

[R] column names in data.frame

Dear R-help, Please can someone explain how to put a column name on an output data.frame. ##Starting with a data.frame with 3 columns (d$Year, d$NoIndiv, d$wtd_tl) yr_ind - split (d$NoIndiv, d$Year) yr_tl - split (d$wtd_tl, d$Year) ann_ind - sapply (yr_ind, sum) ann_tl - sapply (yr_tl, sum)

Professor Ripley, These are optimization problems with multiple local maxima, and like any complex statistical fitting problem you should not expect all programs to give the same answer. Examining the log-likelihoods from the anova statements, while fit1 and m1 are similar, the maximum

[R] probability histogram question

Hello, all; I get an unexpected result when trying to plot a probability histogram with R1.9.1 on windows xp: #with the following code: x - runif(100,0,1) hist(x) hist(x, freq=F) h - hist(x, freq=F) summary(h) #Length Class Mode #breaks 11 -none- numeric #counts 10

apparently not that gives me the following error: Error in names-.default(`*tmp*`, value = c(year, av_t1)) : names attribute [2] must be the same length as the vector [1] presumably because the 2nd column (av_tl) already has a column name, and therefore seems longer? - Original

Alec, Thanks for your reply. I guess what I'm getting at is that I to plot the histogram such that the HEIGHT of each bar represents the proportion of that class in the sample. From your reply I gather that the AREA of each bar is currently representing the proportion. My current work-around

RE: [R] column names in data.frame

Hi Louize, Sorry to lead you astray, but I misinterpreted what you were doing (I could still be leading you astray :-(. You should be able to make a names attribute for d2 by names(d2) - c(year, col2namewhatyouwant, col3namewhatyouwant, ...) to the length of av_t1. When you created the data frame

Re: [R] column names in data.frame

I suspect you are interpreting the column names as a column, whereas in fact you only have a single column data frame, so using names(d2) - whatever will work. Thanks, Alec Alec Stephenson Department of Statistics Macquarie University NSW 2109,
