Off topic:Weibull 3p and Johnson SB cdf

Question

[alinecanetti]

Hi everybody! Could someone help me how to run Weibull 3p (with location parameter) and Johnson SB? I am using fitdistplus package but i am not able to adjust those CDFs, which I think fits better to my data... I am really noob in R, and I`m trying to learn it alone, but I spent all day long searching for that with no success. =( Thank you =)
