onlyData = data.frame(result[3:nrow(result),],stringsAsFactors=FALSE,row.names=NULL)
when the result has 3 rows ,result[3:nrow(result),] will return a object with one dimension witch is not a matrix,then the next code
colnames(onlyData)=colNames
will result a error .
So,the solution will be result[3:nrow(result),,drop=F] which will return a matrix no matter how many rows in result .
