Hopefully this is an easy problem... I'm trying to add a partitioned rank column to a data frame where the rank is calculated separately across a partition by categories, the way you could easily do in SQL. I found this solution in the archives that looked like it might work: http://tolstoy.newcastle.edu.au/R/e11/help/10/09/8675.html The example has a data frame with several car companies,

Hi, is there an R function like sql's TOP key word? I have a dataframe that has 3 columns: company, person, salary How do I get top 5 highest paid person for each company, and if I have fewer than 5 people for a company, just return all of them? Thanks, Richard [[alternative HTML version deleted]]

Hi Everyone, I'm a pretty useless r-er but have data that SPSS etc doesn't like. I've managed to do GLMs for my data, but now need to fit a thin plate spline for my data (arcsine.success~date.num:clutch.size) If anyone has a bit of spare time and could come up with a bit of code I'd be very grateful- I just don't get R language! Thanks Rach -- View this message in context:

Oooh Plate Echo was what people had before digital reverbs! (When they didn't have spring reverb!) - Long ago... They are quite rare now because only big studios had them as they took up a lot of room! (and then they threw them all away) *jealous* Do you really have a plate reverb or just a digital simulation? love Freya --- Robert Voigt <robert.voigt@gmx.de> wrote: > uh, you

Dear Eric: Thank you very much. It works nicely. *Just one more thing;* how to create a new variable (say, *Make*) with *Make = Ford* for the ford brand and *Make = T**oyota* for the toyota brand.

Hello, I'm a student at the University of Klagenfurt / Austria and I need some help ! I have to predict 24 daily load-values. Therefor I got a dataset with following colums: 24 past daily load-values 6 past daily temperature-values My goal is to find a model (GAM with thin plate splines) in R. I found the function "gam" in the R-library "mgcv", but it just fits

Hi Has anyone tried to fit a thin plate spine to a triangular plot before? I'm having trouble working out a piece of code to make it possible with three axes. I have done it before with two axes. I've found a package I prefer that makes triangular plots (plotrix) using the triax.plot() function. An example of some data and the plot follows: graph.data<-data.frame(a=c(9,6.2,

Dear R users, I am a beginner in R trying to apply the thin plate spline method to my climate data. I used the example in R to do so, and the lines seem to run fine ( I am not getting errors) but I am not getting any output in the form of graph or anything. I got a warning message saying that 'surface extends beyond box'. Any help is much appreciated. thanks minti

Hi Does someone knows if there's a function/package that can make thin plate splines ? I've looked in mgcv and splines but I haven't found anything.

Is there a way in Ferret to do something akin to SQL''s "SELECT DISTINCT" query? I have a table with multiple columns, and I would like to search just a couple of them (but index others for other kinds of searches on the table). The two columns I want to search do not have unique values, because the other columns finish specifying the record. Is there a way to avoid picking up

Hi, I am using GAMs (package mgcv) to smooth event rates in a penalized regression setting and I was wondering if/how one can select the order of the derivative penalty. For my particular problem the order of the penalty (parameter "m" inside the "s" terms of the formula argument) appears to have a larger effect on the AIC/deviance of the estimated model than the

Hi, First of all, my apologies for the extension of this message, but it is needeed for you to undertand my problem. Straight to the point: i have this domain in my company running in Samba 3.0.2 My users are: hcoelho, jardim, gamito, yesenia, smatias, fqueiros, faugusto, vamaro, peixinho, aragao, dina, pinho. I have this shares with the users that can access them and the correponding Linux

That probably works in this case, but it would cause grief if another car make had "ford" somewhere inside its name e.g. "bedford". Safer general practice is Auto[Auto$name %in% c("ford", "toyota"),] or similar using subset(). -pd > On 17 Dec 2017, at 09:10 , Eric Berger <ericjberger at gmail.com> wrote: > > myAuto <- Auto[

Dear R gurus, I'm trying to solve what I assume is a fairly simple problem, but I'm having trouble finding the proper approach. I have a matrix where each column is some object (e.g. a car) and each row is a numeric measurement of a feature of said object (e.g. horse power, top speed, etc.). Let's also suppose that I know what make the car is (e.g. toyota, ford, etc.), stored in a
