I’m trying to save my matrix to a file, but a get an error:
“Error in command 'as.data.frame.default(A)': cannot convert class 'structure("dsCMatrix", package = "Matrix")' to class "data.frame"”
I know I cannot use the matrix in write.csv() function but I have a problem converting the matrix into a data frame. Can anyone give me some tips
>Solution :
You get an error because you’re trying to directly convert a sparse matrix into a data frame. You can convert a sparse matrix into a full matrix, and then use as.data.frame() to convert it into a data frame. Then you can save the data frame to a file using the write.csv() command.
But be careful with using as.matrix() as it may consume more memory.
object_df <- as.data.frame(as.matrix(object))
write.csv(object_df, "path/to/save/object.csv")
