R Minimum & Maximum Number of Characters in Column Strings (2 Examples)
In this R tutorial you’ll learn how to return the number of characters in a string in a data frame variable.
Creation of Example Data
my_df <- data.frame(x1 = c("xx", "xxxx", "xxx"), # Example data frame in R x2 = c("y", "yyyy", "yyyyyyy"), x3 = c("zzzz", "zz", "zzzz")) my_df # Showing example data in RStudio console # x1 x2 x3 # 1 xx y zzzz # 2 xxxx yyyy zz # 3 xxx yyyyyyy zzzz |
my_df <- data.frame(x1 = c("xx", "xxxx", "xxx"), # Example data frame in R x2 = c("y", "yyyy", "yyyyyyy"), x3 = c("zzzz", "zz", "zzzz")) my_df # Showing example data in RStudio console # x1 x2 x3 # 1 xx y zzzz # 2 xxxx yyyy zz # 3 xxx yyyyyyy zzzz
Example 1: Find Minimum Number of Characters in String in Data Frame Columns
apply(my_df, # Minimum length 2, function(x) min(nchar(x))) |
apply(my_df, # Minimum length 2, function(x) min(nchar(x)))
Example 2: Find Maximum Number of Characters in String in Data Frame Columns
apply(my_df, # Maximum length 2, function(x) max(nchar(x))) |
apply(my_df, # Maximum length 2, function(x) max(nchar(x)))
