new account here, i just wondering, i have vector called words with contain many words, i just want to find out the longest word based on his length, so i consider using for loop nchar and if to find out the longest word

so after do some desk research, my code will be like this

get.longest.word <- function(words)
    {
    for (i in words){
        if(max(nchar(i)) {
            print(i)
        }
    }
           }

and it returns error

Error in parse(text = x, srcfile = src): <text>:4:26: unexpected '{'
3:     for (i in words){
4:         if(max(nchar(i)) {
                            ^
Traceback:

since im new in R, could you guys pls see my code and where the wrong at?

my vector after i use dput(head(words)) are like this

c("a", "able", "about", "absolute", "accept", "account")
r

A simple approach might be, in base R:

x <- c("cat", "corn", "house")
x[nchar(x) == max(nchar(x))]  # [1] "house"

The above selects all indices of x whose length is equivalent to the max length. It will return ties in the event that two or more words have the same max length.

We could use which with max(nchar())

words <- c("a", "able", "about", "absolute", "accept", "account")

words[which.max(nchar(words))]

[1] "absolute"

Another base R option

v[order(-nchar(v))][1]
