Examples

if (requireNamespace("lattice", quietly = TRUE)) {
dir <- tempfile()
dir.create(dir)
for(i in 1:2) {
pdf(file.path(dir, paste("plot", i, ".pdf", sep = "")))
print(lattice::xyplot(iris[,1] ~ iris[,i], data = iris))
dev.off()
}

output <- tempfile(fileext = '.pdf')
combine_pdf(
   vec_input =
      file.path(dir, paste("plot", 1:2, ".pdf", sep = "")),
   output = output,
   start_pages = c(NA, NA),
   end_pages = c(NA, NA)
