Just a minor point in the suggested solution: df$LAP <- with(df, ifelse(G=='male', (WC-65)*TG, (WC-58)*TG)) since WC and TG are not conditional, would this be a slight improvement? df$LAP <- with(df, TG*(WC - ifelse(G=='male', 65, 58))) -----Original Message----- From: R-help <r-help-bounces at r-project.org> On Behalf Of Jorgen Harmse via R-help Sent: Friday,

I might have factored the gender. I'm not sure it would in any way be quicker. But might be to some extent easier to develop variations of. And is sort of what factors should be doing... # make dummy data gender <- c("Male", "Female", "Male", "Female") WC <- c(70,60,75,65) TG <- c(0.9, 1.1, 1.2, 1.0) myDf <- data.frame( gender, WC, TG ) #

df$LAP <- with(df, ifelse(G=='male', (WC-65)*TG, (WC-58)*TG)) That will do both calculations and merge the two vectors appropriately. It will use extra memory, but it should be much faster than a 'for' loop. Regards, Jorgen Harmse. ------------------------------ Message: 8 Date: Fri, 3 Nov 2023 11:10:49 +1030 From: "Md.

Hello Everyone, I have three variables: Waist circumference (WC), serum triglyceride (TG) level and gender. Waist circumference and serum triglyceride is numeric and gender (male and female) is categorical. From these three variables, I want to calculate the "Lipid Accumulation Product (LAP) Index". The equation to calculate LAP is different for male and females. I am giving both

Well, something like: LAP <- ifelse(gender =='male', (WC-65)*TG, (WC-58)*TG) The exact code depends on whether your variables are in a data frame or list or whatever, which you failed to specify. If so, ?with may be useful. Cheers, Bert On Fri, Nov 3, 2023 at 3:43?AM Md. Kamruzzaman <mkzaman.m at gmail.com> wrote: > Hello Everyone, > I have three variables: Waist

There are many techniques Callum and yours is an interesting twist I had not considered. Yes, you can specify what integer a factor uses to represent things but not what I meant. Of course your trick does not work for some other forms of data like real numbers in double format. There is a cost to converting a column to a factor that is recouped best if it speeds things up multiple times. The

Yes, that will halve the number of multiplications. If you?re looking for such optimisations then you can also consider ifelse(G=='male', 65L, 58L). That will definitely use less time & memory if WC is integer, but the trade-offs are more complicated if WC is floating point. Regards, Jorgen Harmse.

Dear All, I am having a very basic error, but somehow do not know how to resolve it. I've read a dataset in .csv into R with two columns - sector, export. When trying to plot the data it says "sector not found" This is the formula. SouthAfrica<-read.csv(c,header=T) > hist(sector$exports,xlab="exports (MtCO2)",main="CO2 Exports") Error in

Hi, I hope this is the correct mailinglist for my question. I've made a script that sends a file to a NT shared folder. As long as I make a successfull connect, I get return status 0... This is a problem, since now I can't make a correct errorhandling if something goes wrong. +/opt/samba-2.0.5a/bin/smbclient //mapa-lap/mapaPublic -E -d0 -I XXX.YYY.ZZZ.WWW -n mapa-lap -N -U guest -c put

Dear R-Help, I also send the following post by e-mail to you, however I try to post it here aswell. My name is Henrik and I am currently trying to solve a Maximum Likelihood optimization problem in R. Below you can find the output from R, when I use the "BFGS" method: The problem is that the parameters that I get are very unreasonable, I would expect the absolute value of each

I want to make a log-log plot with a regression line, but I can't figure out what I'm doing wrong. What I'm trying is: plot(mass,area, log="xy", pch=as.numeric(food)) abline(lm(mass~area)) or plot(mass,area, log="xy", pch=as.numeric(food)) islands$logmass <- log(mass) islands$logarea <- log(area) attach(islands) abline(lm(logmass~logarea)) But that does

Hi, I've tracked the first problem (mentioned in my previous email, quoted below) down further, ending up in the handling of alloca in LoopRotation.cpp (from trunk): // If the instruction's operands are invariant and it doesn't read or write // memory, then it is safe to hoist. Doing this doesn't change the order of // execution in the preheader, but does

Guys. I have this problem for a long time. In large number of times when I type letter "y", like in "you" my typing cursor jumps 2-3 rows up or 1-2 words to the left. I am unable to understand why. Could it be something with lap-top keyboard? Typing rate? CentOS 5.5 Gnome, I mostly use Firefox and Thunderbird. Ljubomir

Hello, I have compared the potentials of R and Stata about GLMM, analysing the dataset 'ohio' in the package 'faraway' (the same dataset is analysed with GEE in the book 'Extending the linear model with R' by Julian Faraway). Basically, I've tried the 2 commands 'glmmPQL' and 'glmer' of R and the command 'xtmelogit' of Stata. If I'm not

Hi all, A couple of people are trying to convince me to come to FOSDEM in Belgium at the end of February. I''m a bit hesitant because I''ve been doing so much travel, but LinuxConf.au was a great experience and seems to have really helped get exposure to Puppet. There seems to be a pretty strong European contingent of Puppet users, and it''d be great to meet

Are direct bit-rate converters possible for Ogg Vorbis? Or do they already exist? Even more, is it possible to directly convert MP3/ATRAC3 (i.e., Sony Minidisc) encoding to and from Ogg Vorbis? There has been an earlier discussion on this question. But this discussion centered around the fact that people couldn't see the point, and were rather hostile to the idea. There is a very good
