In another method it can also be accomplished simply with help of order () function only. Both the examples are shown below. 1 2 3 4We will use pipe operator "%>%" to feed the data to the dplyr function arrange (). We need to specify name of the variable that we want to sort dataframe. In this example, we are sorting by variable "body_mass_g". 1 2 penguins %>% arrange(body_mass_g) dplyr's arrange () sorts the dataframe by the variable and outputs a new dataframe (as a tibble).Using arrange () sorts cases (rows) by putting specific variables (columns) in specific orders (e.g., ascending or descending). For instance, we could want to arrange cases (rows) by the name of individuals (in alphabetical order). The dplyr function arrange () let's us do this by calling:arrange () orders the rows of a data frame by the values of selected columns. Unlike other dplyr verbs, arrange () largely ignores grouping; you need to explicitly mention grouping variables (or use .by_group = TRUE ) in order to group by them, and functions of variables are evaluated once per data frame, not once per group. UsageHere the first column should be the athlete names, and the remaining columns should correspond to the cities. *Please you the arrange function (2x) to get the columns (beside the Name column) and rows in alphabetical order. Apart from the first column, each entry gives the median time recorded by the athlete in this city.

You can use the following functions to sort values alphabetically in R: #sort values in vector alphabetically sort (x) #sort data frame column alphabetically df [order (df$var1), ] #sort data frame by multiple columns alphabetically df [with (df, order (var1, var2)), ] The following examples show how to use each of these functions in practice.For instance, if R sees it as character data, then the values will be sorted alphabetically.

Some standard R functions for working with factors include. factor creates a factor from another type of variable; levels returns the levels of a factor; reorder changes level order to match another variable @romainfrancois thanks for the clarification---although I would argue that there is clearly a concept of "how they appear in the data" which is why your example using factor() works at all. Using unique() also preserves order, so using converting to factors is not strictly necessary. I was wondering why the decision was made to sort by dictionary order when assigning group ids rather than the ...The most basic way to sort a data frame by a date variable in R is to use the order () function from base R.

Ever since starting to use dplyr extensively a few weeks ago I've been using this "trick" to easily order the levels of a factor based on the row order of a dataframe.
