R: how to display the first n characters from a string of words
Solution 1
The other answers didn't eliminate the spaces as you did in your example, so I'll add this:
strsplit(substr(gsub("\\s+", "", Getty), 1, 10), '')[[1]]
#[1] "F" "o" "u" "r" "s" "c" "o" "r" "e" "a"
Solution 2
Turn your code around and you get what you want.
Getty <- "Four score and seven years ago our fathers brought forth on this continent a new nation, conceived in liberty, and dedicated to the proposition that all men are created equal."
first.10 <- substr(Getty, start=1, stop=10)
first.10
"Four score"
split <- strsplit(first.10, split="")
split
"F" "o" "u" "r" " " "s" "c" "o" "r" "e"
Solution 3
The reason why you got "c(\"F\", \"o\""
is because the strsplit
output is a list
. We can convert the list
to vector
by extracting the first list
element ie. [[1]]
. Use the head
to get the first 10 characters.
head(strsplit(Getty, '')[[1]], 10)
Update
If you just want to extract characters without the spaces,
library(stringr)
head(str_extract_all(Getty, '[^ ]')[[1]],10)
#[1] "F" "o" "u" "r" "s" "c" "o" "r" "e" "a"

I have the following string:
Getty <- "Four score and seven years ago our fathers brought forth on this continent a new nation, conceived in liberty, and dedicated to the proposition that all men are created equal."
I want to display the first 10 characters. So I began by splitting the string into individual characters:
split <- strsplit(Getty, split="") split
I get all the individual characters as this point. Then I make a substring of the first 10 characters.
first.10 <- substr(split, start=1, stop=10) first.10
And here is the output:
"c(\"F\", \"o\""
I am not understanding why this prints out? I thought it would just print out something like:
"F" "o" "u" "r" "s"
Is there a way I can alter my code to print what I have above?
Thank you everyone!
