How to concatenate numerical vectors and a string to return a string in R?
In general, the concatenation of numerical vectors and string results in a vector of strings in R. For example, if we want to concatenate 1, 2, 3 with Tutorialspoint using paste function then it will result in a vector as: "Tutorialspoint 1" "Tutorialspoint 2" "Tutorialspoint 3". But if we want it to return as "Tutorialspoint 1 2 3" then we need to use collapse argument with paste function.
Example1
> x1
Output
[1] "A" "B" "C" "D" "E" "F" "G" "H" "I" "J"
> y1
Output
[1] 1 9 6 3 8 1 8 5 9 1 2 8 3 8 4 5 10 1 6 3 9 8 2 2 3 [26] 7 5 5 1 5 7 10 5 4 8 7 6 4 5 4 10 8 4 7 1 1 3 9 2 3
> paste(c(x1,y1),collapse="")
Output
[1] "ABCDEFGHIJ19638185912838451016398223755157105487645410847113923"
Example2
> x2<-"TutorialsPoint" > x2
[1] "TutorialsPoint"
> y2<-rnorm(50) > y2
