t tests/ANOVA
First check that your data satisfies the normality assumption. If yes,
then start with the ANOVA test
summary( fit <- aov( genomes ~ clonefed ) )
and *if* you find a significant F-value, you can see which difference is
significant. i.e. post-hoc analysis.
TukeyHSD( fit, "clonefed" )
You can use help("aov") etc to find out more details including examples.

I have a set of data that comprises genome numbers in single eggs from three different parasite clones - 3D7, HB3, and MIX. I can draw a boxplot of the genome numbers for each clonefed but how do I carry out a t test or ANOVA to compare if the means are signifcantly different?
