i'm wondering problem.

this has nothing csv file. error message states have embedded nul char in file name: \0 denotes ascii byte == 0, forbidden in r string (internally, denotes end of string).

perhaps meant "\\0laplacian1entropy.csv" or "/0laplacian1entropy.csv". anyway, if wish include backslash in string, must escape with... backslash.
