Re: [R] new_index

Thank you Jeff and all. I wish to go back to my student life. ID is not necessary in dat2, sorry for that. On Sat, Sep 7, 2019 at 5:10 PM Jeff Newmiller wrote: > > Val has been posting to this list for almost a decade [1] so seems unlikely > to be a student... but in all this time has yet t

[R] Fwd: new_index

Hi Val, see below: > dat1 <-read.table(text="ID, x, y, z + A, 10, 34, 12 + B, 25, 42, 18 + C, 14, 20, 8 ",sep=",",header=TRUE,stringsAsFactors=F) > > dat2 <-read.table(text="ID, weight + A, 0.25 + B, 0.42 + C, 0.65 ",sep=",",header=TRUE,stringsAsFactors=F) > > dat3 <- data.frame(ID = dat1[,

Re: [R] new_index

Val has been posting to this list for almost a decade [1] so seems unlikely to be a student... but in all this time has yet to figure out how to post in plain text to avoid corruption of code on this plain text mailing list. The ability to generate small examples has improved, though execution s

Re: [R] new_index

Hello, The problem itself is simple: i <- match(dat1$ID, dat2$ID) colSums(t(dat1[i, -1])*dat2[i, -1]) #1 2 3 #24.58 35.59 17.10 But both dat1 and dat2 are wrong and can be read with read.csv dat1 <- read.csv(text = " ID , x, y, z A, 10, 34, 12 B, 25, 42, 18 C, 14, 20, 8 ", st

Re: [R] new_index

dat1 is wrong also. It should read: dat1 <-read.table(text="ID, x, y, z A, 10, 34, 12 B, 25, 42, 18 C, 14, 20, 8 ",sep=",",header=TRUE,stringsAsFactors=F) Is this a homework problem? This list has a no homework policy. Cheers, Bert Bert

Re: [R] new_index

Hi all Correction for my previous posting. dat2 should be read as dat2 <-read.table(text="ID, weight A, 0.25 B, 0.42 C, 0.65 ",sep=",",header=TRUE,stringsAsFactors=F) On Sat, Sep 7, 2019 at 1:46 PM Val wrote: > > Hi All, > > I have two data frames with thousand rows and several columns.

[R] new_index

Hi All, I have two data frames with thousand rows and several columns. My samples of the data frames are shown below dat1 <-read.table(text="ID, x, y, z ID , x, y, z A, 10, 34, 12 B, 25, 42, 18 C, 14, 20, 8 ",sep=",",header=TRUE,stringsAsFactors=F) dat2 <-read.table(text="ID, x, y, z ID,

You may get a response here (including my poorly-informed one) but this is off topic (_do read the Posting Guide_) so you are basically barking into the darkness here. You should be asking in the RStudio community forum. As far as I am aware you have to run your RSS in a single environment, so c

Dear R-help Mailing List: For reproducibility, I want to use Conda + R (IRkernel), which will allow me to have within the same machine different "environments", with different versions of R installed, and specific package versions: http://know.continuum.io/rs/387-XNW-688/images/conda-cheatsheet.p
