Complete vector of numbers

I have a vector that looks like this:

vector <- c(3.1, 5.3, 5.5)

and I want to fill in the missing numbers, resulting in:

1.0, 2.0, 3.1, 4.0, 5.1, 5.2, 5.3, 5.4, 5.5

or

1.0, 2.0, 3.0, 3.1, 4.0, 5.0, 5.1, 5.2, 5.3, 5.4, 5.5

How can that be done?

>Solution :

library(purrr)

vector <- c(3.1, 5.3, 5.5)

vector %>%
  # add floating point numbers
  # e.g. 3.3 -> c(3.0, 3.1, 3.2, 3.3)
  keep(~ .x %% 1 != 0) %>%
  map(~ {
    a <- as.integer(.x)
    b <- (.x %% 1) * 10 - 1
    a + (seq(0, b) / 10)
  }) %>%
  simplify() %>%
  # add original values
  c(vector) %>%
  c(
    # add integers
    vector %>% as.integer() %>% max() %>% seq()
  ) %>%
  # tidy up
  sort() %>%
  unique()
#>  [1] 1.0 2.0 3.0 3.1 4.0 5.0 5.1 5.2 5.3 5.4 5.5
