vec

class(vec) # Class of example vector

vec_1 ＜- as.numeric(vec) # Apply as.numeric()
vec_1 # Different numbers in output

vec_2 ＜- as.numeric(as.character(vec)) # Apply as.numeric() & as.character()
vec_2 # Same numbers in output

data ＜- data.frame(x1 = factor(c(4, 4, 4, 2, 3, 2)), # Create example data frame
x2 = letters[1:6],
x3 = 6:1)
data

sapply(data, class) # Classes of columns

data_new ＜- data # Convert column to numeric
data_new$x1 ＜- as.numeric(as.character(data_new$x1))
data_new

sapply(data_new, class) # Updated classes
