Programming language in R studio or R, food1 = "Water" food2 = "Melon"
Concatenate = paste("food1","food2"), will give "Water Melon". In excel Water in range("B2"), Melon in range("B3"), use =CONCATENATE(B2, " ", C2) it gives Water Melon.
Explanation:
- R studio is analytical tool which comes from programming S language.
- We need 3 variable Food1,Food2 and Concatenate in R studio.
- Food1 = "Water" inverted commas mean it is character.
- Food2 = "Melon" inverted commas mean it is a character.
- "=" gives a variable notification.
- Concatenate is a variable which we use function paste .
- Concatenate = paste(food1,food2) result "water melon"
- paste(..., sep = "" , collapse = Null)
- It is function from R.
- Excel Water in B2 and Melon in C2 use the formula concatenate.
- =CONCATENATE(B2, " ",C2) in between commas means space.
