Hello,
Here is a way, using logical indices.
b$pheno <- NA
b$pheno[b$FLASER == 1 & b$PLASER == 1] <- 1
b$pheno[b$FLASER == 2 | b$PLASER == 2] <- 2
Hope this helps,
Rui Barradas

Hello,
I have a data frame like this:
head(b)
FID IID FLASER PLASER
1: fam1000 G1000 1 1
2: fam1001 G1001 1 1
3: fam1003 G1003 1 2
4: fam1005 G1005 1 1
5: fam1009 G1009 NA 2
6: fam1052 G1052 1 1
...
unique(b$PLASER)
[1] 1 2 NA
unique(b$FLASER)
[1] 1 2 NA
how can I do if else statement so that I am creating a
PHENO =2 if b$FLASER=2 or b$PLASER=2
PHENO=1 if b$FLASER=1 and b$PLASER=1
otherwise PHENO=NA
I tried this but I am not sure if this is correct:
b$pheno=ifelse(b$PLASER==1 & b$FLASER==1,1,ifelse(b$PLASER==2 |
b$FLASER==2,2,NA))
Thanks
Ana
