Hi, and welcome!
Please see the FAQ: What's a reproducible example (`reprex`) and how do I do one? Using a reprex, complete with representative data will attract quicker and more answers.
From the tidyr package documentation, here's one way to drop NAs
suppressPackageStartupMessages(library(dplyr))
suppressPackageStartupMessages(library(tidyr))
df <- tibble(x = c(1, 2, NA), y = c("a", NA, "b"))
df %>% drop_na()
#> # A tibble: 1 x 2
#> x y
#> <dbl> <chr>
#> 1 1 a
df %>% drop_na(x)
#> # A tibble: 2 x 2
#> x y
#> <dbl> <chr>
#> 1 1 a
#> 2 2 <NA>
