Hi,

ggpubr is a good solution :

library("ggpubr")
manchots = palmerpenguins::penguins
var_num = names(manchots)[sapply(manchots, is.numeric)]
graphiques = as.list(numeric(6))

k = 0
for (i in seq_along(var_num)) {
  for (j in seq_len(i-1)) {
    k = k+1
    graphiques[[k]] = ggplot(manchots, aes_string(var_num[i], var_num[j], col = "species")) + geom_point()
  }
}

gg = ggarrange(plotlist = graphiques, ncol = 2, nrow = 1, common.legend = TRUE)      
ggexport(filename = "test.pdf", plotlist = gg, width = 12, height = 6)
