Regarding file format as input

[prakritishar]

I am trying to use Funmap2 for my analysis in grapevine. But when I use FM2.load.data I get error message "Error in read.table(file = file, header = header, sep = sep, quote = quote, : 'file' must be a character string or connection".

I do have three CSV file data frame for phenotype, genotype and marker placed as in form at required. Only difference I noticed is genotype file numeric conversion where in example as 3 numeric format ( assigned for AA, Aa and aa ) while I am using 4 number format for AC,AD,BC,BD.

Is there any issue why function call not reading data input files?

Any suggestions would be great
