I might be silly but if I was going to type in dput() then how should I send
the data over here?
Cut and paste. For example, if I have a dataframe named x and type
dput(x), I see
structure(list(a = 1:10), .Names = "a", row.names = c(NA, -10L
), class = "data.frame")
If you run
x <- structure(list(a = 1:10), .Names = "a", row.names = c(NA, -10L
), class = "data.frame")
you'll get a dataframe that looks just like mine. Then you can start to
answer questions about it.
I can't do anything with your jpeg to answer your questions about your
dataframe.

but there was something wrong. I'll show how I did step by step.
