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

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.

Domi
