Autocomplete when using RStudio

Question

I recently started using R and found out about Hadley ggplot2 and other packages. Now the good part is that its packages do not require us to write datasetname $ xyz (or if we use "c" or "attach"), but the bad part is that R-Studio auto-complete does not recognize column names. Some of the columns I work with have long names, and I often make mistakes when typing them.

Is there any solution that will allow me to use the Hadley package or "with" / "attach" without losing the autocomplete function?

I am a beginner, so I will be grateful for any thoughts.

For example, here's what my data looks like:

acctnum gender state   zip zip3 first last book_ nonbook_ total_ purch child youth cook do_it refernce art geog buyer
1   10001      M    NY 10605  106    49   29   109      248    357    10     3     2    2     0        1   0    2    no
2   10002      M    NY 10960  109    39   27    35      103    138     3     0     1    0     1        0   0    1    no
3   10003      F    PA 19146  191    19   15    25      147    172     2     0     0    2     0        0   0    0    no
4   10004      F    NJ 07016  070     7    7    15      257    272     1     0     0    0     0        1   0    0    no
5   10005      F    NY 10804  108    15   15    15      134    149     1     0     0    1     0        0   0    0    no
6   10006      F    NY 11366  113     7    7    15       98    113     1     0     1    0     0        0   0    0   yes

Now, if I use ttest using $,

using $ sign
