How to converst a character vector to numeric in R in the R programming language. More details: statisticsglob...
R code of this video:
vec ＜- as.character(c(5, 3, 6, 3, 6, 6, 5)) # Create example vector
vec
class(vec) # Class of example vector
vec_num ＜- as.numeric(vec) # Apply as.numeric()
vec_num
class(vec_num) # Class of new vector
data ＜- data.frame(x1 = as.character(c(4, 4, 4, 2, 3, 2)), # Create example data frame
x2 = 6:1,
x3 = as.character(1:6))
data
sapply(data, class) # Classes of columns
data_new1 ＜- data # Convert one column to numeric
data_new1$x1 ＜- as.numeric(data_new1$x1)
data_new1
sapply(data_new1, class) # Updated classes
data_new2 ＜- data # Change all character columns
char_columns ＜- sapply(data_new2, class) == "character"
data_new2[ , char_columns] ＜- sapply(data_new2[ , char_columns], as.numeric)
data_new2
sapply(data_new2, class) # Updated classes
