How to separate first text value and the remaining text in an R vector?
To separate first text value and the remaining text in an R, we can follow the below steps −
First of all, create a vector.
Then, use str_split function from stringr package to separate first text value and the remaining text.
Example
Create the vector
Let’s create a vector as shown below −
x<-sample(c("Data","Machine
Learning","Python","R","Java","SQL","Tableu"),25,replace=TRUE)
xOutput
On executing, the above script generates the below output(this output will vary on your system due to randomization) −
[1] "Python" "Python" "Machine
Learning" [4] "Python" "Java" "Python" [7] "Java" "SQL" "R" [10] "Data" "Tableu" "Python" [13] "Machine
Learning" "R" "Machine
Learning" [16] "Machine
Learning" "Java" "Tableu" [19] "Data" "Tableu" "R" [22] "Java" "Machine
Learning" "Python" [25] "Tableu"
Subset first value and rest of the text in string vector
Using str_split function from stringr package to subset first text value and the remaining text in each element of vector x −
x<-sample(c("Data","Machine
Learning","Python","R","Java","SQL","Tableu"),25,replace=TRUE)
library(stringr)
str_split(x,"(?<=.{1})",2)Output
[[1]] [1] "D" "ata" [[2]] [1] "T" "ableu" [[3]] [1] "M" "achine Learning" [[4]] [1] "J" "ava" [[5]] [1] "J" "ava" [[6]] [1] "P" "ython" [[7]] [1] "J" "ava" [[8]] [1] "M" "achine Learning" [[9]] [1] "R" "" [[10]] [1] "R" "" [[11]] [1] "R" "" [[12]] [1] "M" "achine Learning" [[13]] [1] "P" "ython" [[14]] [1] "T" "ableu" [[15]] [1] "M" "achine Learning" [[16]] [1] "J" "ava" [[17]] [1] "J" "ava" [[18]] [1] "D" "ata" [[19]] [1] "T" "ableu" [[20]] [1] "D" "ata" [[21]] [1] "T" "ableu" [[22]] [1] "T" "ableu" [[23]] [1] "T" "ableu" [[24]] [1] "T" "ableu" [[25]] [1] "T" "ableu"
