Hey,

When we check the normality of the data using shapiro test I got error massage as **"Error in FUN(dd[x, ], ...) : all 'x' values are identical".** When I checked my data set it contain with the 0 values for that variables. Do we unable to check the normality of that data in RStudio due to the identical values of variables. So how could I solve this problem. Please give me some guidance.

Thanks,
