Hello everybody, I would like to replace or recode a list of numbers between 1 and 12 (total 100). I have tried to make it with recode, but i have two types of replacements. For 1,2,3,4,11,12 => invierno and for 5,6,7,8,9 and 10 => verano. recode(datos.mx1[,7], "1='invierno'; 2='invierno'; 3='invierno';4='invierno';11='invierno';12='invierno'") #with this command it works perfectly, but i have only one part recode(datos.mx1[,7], "'5'='verano'; '6'='verano'; '7'='verano';'8'='verano';'9'='verano';'10'='verano'") #when i run this command it works also fine, but it clears the first change above. I had previously tried it with the if-command, but it doesn't work. I hope someone can help me. Thank you very much. Domi [[alternative HTML version deleted]]
HI, Try this: set.seed(1) ?df1<-data.frame(colA=sample(1:100,n,replace=TRUE)) numbers1<-c(1,2,3,4,11,12) ?numbers2<-c(5,6,7,8,9,10) ?df1$colA[df1$colA%in%numbers1]<-"invierno" ?df1$colA[df1$colA%in%numbers2]<-"verano" ?head(df1,10) ???? colA 1????? 27 2????? 38 3????? 58 4????? 91 5????? 21 6????? 90 7????? 95 8????? 67 9????? 63 10 verano A.K. ----- Original Message ----- From: Dominic Roye <dominic.roye at gmail.com> To: r-help at r-project.org Cc: Sent: Saturday, August 11, 2012 3:10 PM Subject: [R] replace funcion Hello everybody, I would like to replace or recode a list of numbers between 1 and 12 (total 100).

HI,
I guess this should also work.
set.seed(1)
?df1<-data.frame(colA=sample(1:100,n,replace=TRUE))
numbers1<-c(1,2,3,4,11,12)
?numbers2<-c(5,6,7,8,9,10)
df1[df1$colA%in%numbers1,]<-"invierno"
df1[df1$colA%in%numbers2,]<-"verano"
#or
set.seed(1)
?df1<-data.frame(colA=sample(1:100,n,replace=TRUE))
within(df1,{colA[colA%in%numbers1]<-"invierno";colA[colA%in%numbers2]<-"verano"})
A.K.

Subject: [R] replace funcion
Hello everybody,
I would like to replace or recode a list of numbers between 1 and 12 (total
100). I have tried to make it with recode, but i have two types of
replacements. For 1,2,3,4,11,12 => invierno and for 5,6,7,8,9 and 10 =>
verano.
recode(datos.mx1[,7], "1='invierno'; 2='invierno';
3='invierno';4='invierno';11='invierno';12='invierno'")?
#with this command
it works perfectly, but i have only one part
recode(datos.mx1[,7], "'5'='verano';
'6'='verano';
'7'='verano';'8'='verano';'9'='verano';'10'='verano'")
#when i run this
command it works also fine, but it clears the first change above.
I had previously tried it with the if-command, but it doesn't work. I hope
someone can help me. Thank you very much.

Hello, Try the following, using index vectors, not recode(). inx <- datos.mx1[, 7] %in% 5:10 datos.mx1[inx, 7] <- "verano" datos.mx1[!inx, 7] <- "invierno" Hope this helps, Rui Barradas Em 11-08-2012 20:10, Dominic Roye escreveu:> Hello everybody, > > > I would like to replace or recode a list of numbers between 1 and 12 (total > 100).
