Help with ANOVA Analysis of Data

I need to compute:

The sum of squares associated with sex from the ANOVA table;
Create histograms of the data used in the ANOVA for each level of Sex independently. Using this output and boxplot and apply do you think the assumptions of ANOVA have been met?

How do I input the data of gender? It just keeps coming up as errors on R, and on the online ANOVA calculators, it says all data must be in numbers.
The categories are: WitnessID, Sex, EstTotalLength1, EstTotalLength2, and EstTotalDistance
