Hi,


I agree with Sarah that read.table() will much easier in this case.
If you want scan(), then you can try this:
dat1<-scan(what=list("numeric","character","character","numeric"),text="
id??? name??? sex??? age
111??? HELEN??? f??? 22
112??? DONNA??? f??? 22
113??? ERIC??? m??? 21
114??? LINDA??? f??? 23
115??? AXEL??? m??? 27
116??? Madhuri??? f??? 32
117??? Tarun??? m??? 39
118??? Aashirya??? f??? 23
119??? Nachik??? m??? 24
120??? Leena??? f??? 32
",sep="",skip=2)
dat2<-do.call(data.frame,dat1)
colnames(dat2)<-c("id","name","sex","age")
dat2<-within(dat2,{id<-as.numeric(as.character(id));name<-as.character(name);sex<-as.character(sex);age<-as.numeric(as.character(age))})
?str(dat2)
#'data.frame':??? 10 obs. of? 4 variables:
# $ id? : num? 111 112 113 114 115 116 117 118 119 120
# $ name: chr? "HELEN" "DONNA" "ERIC" "LINDA" ...
# $ sex : chr? "f" "f" "m" "f" ...
# $ age : num? 22 22 21 23 27 32 39 23 24 32
