如何将R列表保存为csv或Excel文件？

my_list <- list(a = c(1, 2, 3), b = c("x", "y", "z"))
write.csv(my_list, file = "my_list.csv")

my_list <- list(a = c(1, 2, 3), b = c("x", "y", "z"))
write.table(my_list, file = "my_list.csv", sep = ",", col.names = NA, quote = FALSE)

install.packages("openxlsx")

library(openxlsx)
my_list <- list(a = c(1, 2, 3), b = c("x", "y", "z"))
write.xlsx(my_list, file = "my_list.xlsx")
