Implement a simple rounding function. The default round function in R uses the IEC 60559 standard therefore it rounds 0.5 to 0 and round -1.5 to -2. The roundx rounding function accounts for this and helps to round 0.5 up.
You can install the development version of roundyh like so:
install.packages('roundyh')
library(roundyh)
roundx(10.111, 1)
#> [1] 10.1
roundx_df(data.frame(c(1.111, 1, 1.11), c(1, 1, 1), c("a", "b", "c")), 1)
#> c.1.111..1..1.11. c.1..1..1. c..a....b....c..
#> 1 1.1 1 a
#> 2 1.0 1 b
#> 3 1.1 1 c
These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
