Hi,
May be this helps.
set.seed(29)
GLSS<- data.frame(hhid=sample(1:10,30,replace=TRUE),value=rnorm(30))
IDstoSelect<- c(1,5,7)
GLSS[!is.na(match(GLSS[,1],IDstoSelect)),]
# hhid value
#1 1 -0.34216061
#6 1 0.28240263
#14 7 0.04197496
#17 7 0.15005878
#21 7 -1.18640939
#22 7 -0.68378601
#25 7 -2.43423380
#27 5 0.95672044
#29 7 1.76127732
#or
GLSS[GLSS[,1]%in% IDstoSelect,]
# hhid value
#1 1 -0.34216061
#6 1 0.28240263
#14 7 0.04197496

Hello,
i have a dataset GLSS in which one of the variables is household
id (GLSS$hhid). Now i have a variable selecting which households i want
to use in a subset (glss1H1). How do I select in an easy way the
household id's that need to go to my subset?
Would be great if someone can give me a help. Thanks!
