🚀 Package Installation and Setup
📦 Package Management
The evanverse package provides robust package management utilities:
# Check if packages are installed
required_packages <- c("dplyr", "ggplot2", "tidyr")
check_pkg(required_packages)
#> # A tibble: 3 × 4
#> package name installed source
#> <chr> <chr> <lgl> <chr>
#> 1 dplyr dplyr TRUE CRAN
#> 2 ggplot2 ggplot2 TRUE CRAN
#> 3 tidyr tidyr TRUE CRAN
# Get package version (skip on CRAN due to network dependency)
if (!identical(Sys.getenv("NOT_CRAN"), "false")) {
