filling in missing data in R

I have a dataset like this 

pos value   
1 20
2 30
4 50
5 50
9 30

You will note that 3, 6,7,8 positions and respective value entries are missing. I would like to fill them in with values corresponding to 0 so that the data looks like this

pos value   
1 20
2 30
3 0
4 50
5 50
6 0
7 0
8 0
9 30

Any ideas on how to achieve this in R?

We can use complete from tidyr

library(tidyr)
df1 %>% 
   complete(pos = full_seq(pos, 1), fill = list(value=0))
# A tibble: 9 × 2
#     pos value
#   <dbl> <dbl>
#1     1    20
#2     2    30
#3     3     0
#4     4    50
#5     5    50
#6     6     0
#7     7     0
#8     8     0
#9     9    30

If we want to continue until 20

df1 %>%
   complete(pos = full_seq(c(pos,20), 1), fill = list(value=0))
