Hi,
May be this helps:
vec1 <- c("Humanities, Multidisciplinary; Social Sciences,
Interdisciplinary; History",
"History","Sociology; Religion","Humanities,
Multidisciplinary;","Social Sciences,
Interdisciplinary","Literature","Sociology; Religion")
res1 <- as.data.frame(table(unlist(strsplit(vec1,split="; ?"))))
#or
?res2 <-
as.data.frame(table(strsplit(gsub(";+",";",paste(vec1,collapse=";
")),"; ?")[[1]]))
?identical(res1, res2)
#[1] TRUE
Regarding sorting, check ?sort() or ?order.
res2[order(res2$Var1),]
A.K.
Hi, I'm new user to R.
I've a list of terms in vector x, for example:
1 Humanities, Multidisciplinary; Social Sciences, Interdisciplinary; History
2 History
3 Sociology; Religion
4 Humanities, Multidisciplinary; Social Sciences, Interdisciplinary
5 Literature
6 Sociology; Religion
I need split for ';' the variable x, sort by name or by count, into new
variable and count. For example:
Humanities, Multidisciplinary 2
History 2
Sociology 2
Religion 2
Literature 1
Social Sciences, Interdisciplinary 2
I don't know how many time ";" appears
Thanks.
