I have created a data matrix from a CSV file In R. But whenever I try saving the data matrix in .RData format or CSV format and reload it again, the "is.numeric(data_matrix) returns FALSE. the argument returned TRUE before saving in CSV or RData format.
The commands i tried for saving are:
write.csv(data_matrix, file = "matrix.csv") #not numeric
write.csv(data_matrix, "data.csv", row.names = FALSE, col.names = FALSE) #matrix numeric but column names changed to 1,2,3,4.....
write.csv(data_matrix, "data.csv", row.names = TRUE) #not_numeric
The commands used for reloading are:
data
I downloaded your CSV and tried to read it. I think the read data are in numeric type.
