I'd like to convert the data frame my df
df <- read.csv("https://raw.githubusercontent.com/Leprechault/trash/refs/heads/main/Dados_C3_data_planta.csv", sep=";")
head(df)
# Data GLY_PN CRO_P MIPU_P CEN_P POA01_P CECRO_P COM_P MOR_PN

to class [1] "matrix" "array". I cannot bring it to work with as.matrix() or data.matrix().
Desirable output (~df_to_matrix()):

class(df_to_matrix)
[1] "matrix" "array"
Column name in the first column and values in numeric format.
# Load the data
df <- read.csv("https://raw.githubusercontent.com/Leprechault/trash/refs/heads/main/Dados_C3_data_planta.csv", sep=";")
# Convert to matrix, excluding the first column (dates)
df_to_matrix <- as.matrix(df[, -1]) # Exclude the first column
# Optionally, convert character columns to numeric
df_to_matrix <- apply(df_to_matrix, 2, as.numeric)
# Check the class
class(df_to_matrix)
# Print the resulting matrix
print(df_to_matrix)
