Hi @pete_reis, you can get a better response if you put more information about your problem, like the data example.
For now I can understand that you have difficulties with the column names when using the t.test(). Check that you are using the column names of your data.

you_data 

names(you_data ) # check the letters, spaces y other symbol.

# `Liveweight change kg/day` For this you need put in backtick because have a /.

t.test(Starch ~ `Liveweight change kg/day`, data = you_data) #
