Sort the column of dataframe in R

To sort the column of dataframe in R we use order() function, with the help of order() function we can sort the column in descending order or ascending order. Let’s see how to

  • Sort the column of dataframe in R in ascending order
  • Sort the column of dataframe in R in descending order

Let’s first create the dataframe.

df1= data.frame(Name=c('James','Paul','Richards','Marico','Samantha','Ravi','Raghu','Richards','George','Ema','Samantha','Catherine'),
                State=c('Alaska','California','Texas','North Carolina','California','Texas','Alaska','Texas','North Carolina','Alaska','California','Texas'),
                Sales=c(14,24,24,32,13,7,9,41,18,16,28,14))
df1

So the resultant dataframe will be

Sort the column of dataframe in R 1

 

Sort the column of dataframe in R by ascending order:

Sorting the column is done with the help of order function. Default is ascending order

## Sort the column by ascending

df2 <- df1[order(df1$Sales),] 
df2

So the sorted dataframe will be

Sort the column of dataframe in R 2

 

Sort the column of dataframe in R by descending order:

Sorting the column is done with the help of order function, specifying minus symbol orders the column in descending order as shown

## Sort the column by descending

df2 <- df1[order(-df1$Sales),] 
df2

So the sorted dataframe will be

Sort the column of dataframe in R 3

 

Sort by multiple column of dataframe in R:

In below example lets first sort by column “state” in ascending order and then sort by “sales” in descending order

## Sort by multiple column 

df2 <- df1[order(df1$State,-df1$Sales),]
df2

So the sorted dataframe will be
