How to get mode (the most frequent value in distribution)?
Hello!
I have a continous distribution and would like to get mode (the most
frequent value in distribution). I easily found mean, median and other
basic thing but not mode function. Can anyone help?
I know there my might be problems with multiple modes, but still I think
that there should be a mode function in R.
Please send mail to R-help list and me, so I can get response faster.
Thank

Efficient subsetting
Hi, I'm facing this problem quite a lot, so it seems worthwhile
to check to see what the most efficient solution is.
I've two vectors x (values ordered) and y. I've ranges
x < x0, x0 <= x < x1, x1 <= x < x2, x2 <= x < x3, x > xn
and want to construct a subvector yprime of y which consists
of the first/last value of y whose x values are in the range.

R: Grouping columns in a data frame based on the values of a column
Perhaps using 'ave' and 'cut':
df <- data.frame(x=runif(100, 0.1, 1), y=rnorm(100, 0.2, 0.6))
df$xcut<-cut(df$x, seq(0, 1, 0.1))
df$z<-ave(df$y, df$xcut)
df[order(df$x),]

recoding variables
Hi,
I was hoping someone could help me. I am a graduate student new to using R, and I'm trying to figure out how to recode a continuous variable to make it into an ordinal variable with 3 categories. I literally have no idea how to proceed--could anyone possibly advise me? Please copy me on any responses, as I have just subscribed to the R-help email list but don't know whether the

función recode
Buenos días
No sé qué es lo que estoy haciendo mal al aplicar la función recode.
Escribo:
personas_LR2 <-recode(personas_LR$edad, '0:15="Menores de 16 años"; 16:44="Entre 16 y 44 años"; 45:64="Entre 45 y 64 años";>=65"65 y más años";', as.factor.result=TRUE)
y me da el siguiente error:
