Is there a way of reading in a file in a way that each line becomes a vector:
for example:
meals.txt
breakfast bacon eggs sausage
lunch sandwich apple marsbar crisps
dinner chicken rice custard pie
I want to read in this file and end up with 3 different vectors, one called
breakfast which contains "bacon", "eggs", sausage" One called lunch with
"sandwich", "apple"... etc
So is there a way to do this with a file like this?
There are very many ways.
Perhaps one of the simplest is to use readLines() to get a character
vector of one element per line, then strsplit() to split the line on
whatever the separator used is. E.g.
meals <- readLines("meals.txt")
m2 <- strsplit(meals, " +")
names(m2) <- sapply(m2, `[`, 1)
m3 <- lapply(m2, `[`, -1)
m3
$breakfast
[1] "bacon" "eggs" "sausage"
$lunch
[1] "sandwich" "apple" "marsbar" "crisps"
$dinner
[1] "chicken" "rice" "custard" "pie"
