A more convenient method can convert a string with any number of words to a list, is to first unlist your "result", then convert that vector to a list:

str <- "qwerty keyboard"
result <- strsplit(str,"[[:space:]]")

# Then convert result to a list
lapply(unlist(result), function(x) x)
> 
[[1]]
[1] "qwerty"

[[2]]
[1] "keyboard"

As an alternative to strsplit(), you can make a list out of the result from scan().

as.list(scan(text=str, what=""))
# Read 2 items
# [[1]]
# [1] "qwerty"
#
# [[2]]
# [1] "keyboard"

try: 

str <- "qwerty keyboard"
result_1 <- strsplit(str,"[[:space:]]")[[1]][1]
result_2 <- strsplit(str,"[[:space:]]")[[1]][2]
result <- list(result_1,result_2)

Or

as.list(strsplit(str, '\\s+')[[1]])
