R sort() Function: Descending Order
In R language, we can use the sort() function to sort vectors or data frames in descending order. Here is a simple example:
# 创建一个向量
x <- c(10, 5, 8, 3, 2)
# 对向量进行从大到小的排序
sorted_x <- sort(x, decreasing = TRUE)
# 打印排序后的向量
print(sorted_x)
After running the above code, the vector will be output in descending order.
[1] 10 8 5 3 2
To sort a column in a data frame, you can use the following sample code:
# 创建一个数据框
df <- data.frame(x = c(10, 5, 8, 3, 2), y = c("a", "b", "c", "d", "e"))
# 对数据框的x列进行从大到小的排序
sorted_df <- df[order(-df$x), ]
# 打印排序后的数据框
print(sorted_df)
After running the above code, the output will display the result of sorting the data frame in descending order based on the x column.
