How to convert character vectors,
How to convert character vectors, data frame columns and variables to the factor class in the R programming language. More info: https://statisticsglobe.com/convert-c...
R programming code:
##### Example 1
vec ＜- c("A", "B", "A", "D", "C", "B") # Create example vector
class(vec) # Check class of vector
vec_updated ＜- as.factor(vec) # Convert character vector to factor
class(vec_updated)
##### Example 2
data ＜- data.frame(x1 = 1:5, # Create example data frame
x2 = letters[1:5],
x3 = c(4, 1, 5, 3, 1),
x4 = c("Male", "Female", "Male", "Male", "Female"),
stringsAsFactors = FALSE)
data # Print example data frame
data2 ＜- data # Replicate example data frame
class(data2$x2) # Check class of second column
data2$x2 ＜- as.factor(data2$x2) # Convert character column to factor
class(data2$x2) # Check class of second column
##### Example 3
data3 ＜- data # Replicate example data frame
str(data3) # Check class of all columns
data3 ＜- as.data.frame(unclass(data3), # Convert all columns to factor
stringsAsFactors = TRUE)
str(data3) # Check class of all columns

class(data2$x2) # Check class of second column
data2$x2 ＜- as.factor(data2$x2) # Convert character column to factor
class(data2$x2) # Check class of second column

data3 ＜- as.data.frame(unclass(data3), # Convert all columns to factor
