How to use tidyr package In R Language
The tidyr package in R is used to mutate and visualize the data. It is used to tidy up the data. The package can be downloaded and installed into the working space using the following command:
install.packages("tidyr")
The separate method in R can be used to split up the specified string column or vector into corresponding sub-parts. The length of the second argument vector is equivalent to the number of pieces to split up the data into.
Syntax:
separate(str, n, pattern)
Parameter:
- str: The string vector to be split.
- n: The names of pieces to split the string into.
- pattern: Pattern to split up the string by.
Example: Split dataframe variable into multiple columns
R
library("tidyr")# creating a dataframe data_frame <- data.frame( col1 = c("val_1","val_2","val_3","val_4") )print("Original DataFrame")print(data_frame)# splitting values in columnprint("Modified DataFrame")data_frame %>% separate(col1, c("col1", "col2"), "_") |
Output:
[1] "Original DataFrame" col1 1 val_1 2 val_2 3 val_3 4 val_4 [1] "Modified DataFrame" col1 col2 1 val 1 2 val 2 3 val 3 4 val 4
