Append Characters in Front of Numeric Data Frame Variable in R (Example Code)

In this R tutorial you’ll learn how to append characters at the beginning of a numeric data frame variable.

Introduction of Example Data

data(iris)                           # Loading an exemplifying data frame
head(iris)
#   Sepal.Length Sepal.Width Petal.Length Petal.Width Species
# 1          5.1         3.5          1.4         0.2  setosa
# 2          4.9         3.0          1.4         0.2  setosa
# 3          4.7         3.2          1.3         0.2  setosa
# 4          4.6         3.1          1.5         0.2  setosa
# 5          5.0         3.6          1.4         0.2  setosa
# 6          5.4         3.9          1.7         0.4  setosa

Example: Adding Characters to Numeric Column Using the paste0() Function

iris_upd <- iris                     # Creating new data frame with characters
iris_upd$Sepal.Length <- paste0("char",
                                iris_upd$Sepal.Length)
head(iris_upd)
#   Sepal.Length Sepal.Width Petal.Length Petal.Width Species
# 1      char5.1         3.5          1.4         0.2  setosa
# 2      char4.9         3.0          1.4         0.2  setosa
# 3      char4.7         3.2          1.3         0.2  setosa
# 4      char4.6         3.1          1.5         0.2  setosa
# 5        char5         3.6          1.4         0.2  setosa
# 6      char5.4         3.9          1.7         0.4  setosa
