convert character matrix to numeric in r

You can convert a character matrix to a numeric matrix in R using the as.numeric() function. Here's an example:

main.r
# Create a sample character matrix
char_matrix <- matrix(c("1", "2", "3", "4"), nrow = 2)

# Convert the character matrix to numeric
numeric_matrix <- as.numeric(char_matrix)

numeric_matrix
191 chars
8 lines

In this example, the elements "1", "2", "3", "4" in the character matrix are converted to numeric values.

It is important to note that for this conversion to work correctly, all elements in the character matrix should be convertible to numeric values.
