How to convert NUM to INT in R?

int, r, type-conversion

Solution

Use `as.integer`:

set.seed(1)
x <- runif(5, 0, 100)
x
[1] 26.55087 37.21239 57.28534 90.82078 20.16819


as.integer(x)
[1] 26 37 57 90 20

Test for class:

xx <- as.integer(x)
str(xx)
 int [1:5] 26 37 57 90 20

Problem

I am trying to convert numeric format to an integer in R. This is essential to a part of the project where I am using java code to run some simulations (which reads this particular data as int). I tried both `round(x$var, 0)` and `trunc(x$var)`. Both of them run successfully, but when I `str(x)`, `x$var` is still `num`. x is a dataframe.
