Add new columns to a data frame that are functions of existing columns with mutate . Use the split-apply-combine concept for data analysis. Use summarize

Explicitly give mutate() a vector with an element for each row in the tibble. Create a vector using a vector function like + or case_when() . The purrr map functions

Notice how the mutate() above returns the whole tibble with a new column called measurement/2. This is quite nice of mutate(), but it would be best to give columns names that don’t include characters other than letters, numbers, underscores (_) or dots (.). So let’s assign a more standard name for this new column: The following R programming syntax shows how to use the mutate function to create a new variable with logical values. For this, we need to specify a logical condition within the mutate command: data %>% # Apply mutate mutate ( x4 = ( x1 == 1 | x2 == "b" ) ) # x1 x2 x3 x4 # 1 1 a 3 TRUE # 2 2 b 3 TRUE # 3 3 c 3 FALSE # 4 4 d 3 FALSE # 5 5 e 3 FALSE 4.5.1 Mutate. Let’s say we wish to look at gdp on a logarithmic scale. This is easily doable with mutate.

You were for example born with between 10 and 100 new mutations in your DNA. Mutation is usually a random process 2018年5月20日我想使用dplyr mutate() 在数据框中创建多个新列。列名和它们的内容应该是动态生成的。示例数据： require(dplyr) data(iris) iris <- tbl_df(iris).

4.5.1 Mutate. Let’s say we wish to look at gdp on a logarithmic scale. This is easily doable with mutate. Note the slightly different syntax, where you have to express the name of the new variable and assign using a single ‘=’ instead of the assignment operator (<-).

The mutate function lets you create a new variable for your dataframe. Apparently, the mutate and select operations are the slowest in comparison, I think, because both the dict and data.table approach work by reference while probably some copying is done in the dplyr pipe.

R offers many ways to recode a column. Here we will see a simple example of recoding a column with two values using dplyr, one of the toolkits from tidyverse in R. df %>% mutate(sex=recode(sex, `1`="Male", `2`="Female")) name sex age John Male

Als Beispiel wollen wir die Punkte im Therapiedatensatz in Prozentwerte umrechnen. Zunächst erstellen wir eine Funktion, die die Aufgabe hat, die Punkte in einen Prozentwert zu transformieren. R Data Frame Example. Finally we can use mutate! Recall that mutate is used to create a new variable from the data.

Then we can use the mutate function as follows: mutate (data, x3 = x1 + x2) # Apply mutate function # x1 x2 x3 # 1 1 5 6 # 2 2 6 8 # 3 3 7 10 # 4 4 8 12 # 5 5 9 14 The mutate() function can also be used to create a new column with a single constant value; which in return can be used to calculate a difference for each of the existing dates: library (lubridate) typesdata %>% mutate ( reference_date = ymd_hm ( "2020-01-01 12:00" ), dates_difference = reference_date - date) %>% select (date, reference_date, dates_difference) mutate () is a function you will use a lot.
