Append value to empty vector in R?

921 Asked by FujiwaraBan in Data Science , Asked on Jun 3, 2021

I'm trying to learn R and I can't figure out how to append to a list.

If this were Python I would . . .

#Python
vector = []
values = ['a','b','c','d','e','f','g']
for i in range(0,len(values)):
    vector.append(values[i])

How do you do this in R?

#R Programming
> vector = c()
> values = c('a','b','c','d','e','f','g')
> for (i in 1:length(values))
+ #append value[i] to empty vector

To append values to an empty vector, use the for loop in R in any one of the following ways:

vector = c()

values = c('a','b','c','d','e','f','g')

for (i in 1:length(values))

  vector[i] <- values[i]

OR

for (i in 1:length(values))

  vector <- c(vector, values[i])

Output:

vector
