Here are my R session information:
> sessionInfo()
R version 3.3.0 alpha (2016-03-24 r70373)
Platform: x86_64-apple-darwin13.4.0 (64-bit)
Running under: OS X 10.11.4 (El Capitan)
locale:
[1] fr_FR.UTF-8/fr_FR.UTF-8/fr_FR.UTF-8/C/fr_FR.UTF-8/fr_FR.UTF-8
If the help is displayed within the R gui using:
help(package='packrat')
The Rlogo.svg is scaled correctly.
However if the help is shown within Rstudio, the Rlogo.svg is not scaled
corrected and is shown at huge size.
The choice of logo displayed in the help comes from the file in folder
html within each package. For example for package numDeriv, within the
file:
/Library/Frameworks/R.framework/Versions/3.3/Resources/library/numDeriv/html/00Index.html
There is this link:
</head><body>
<h1> Accurate Numerical Derivatives
<img class="toplogo" src="../../../doc/html/logo.jpg" alt="[R logo]" />
</h1>
Whereas for packrat package, within the file
/Library/Frameworks/R.framework/Versions/3.3/Resources/library/packrat/html/00Index.html
The link is this one:
</head><body>
<h1> A Dependency Management System for Projects and their R Package
Dependencies
<img class="toplogo" src="../../../doc/html/Rlogo.svg" alt="[R logo]" />
</h1>
And the Rlogo.svg is badly scaled in Rstudio Version 0.99.1119 (beta) or
in public 0.99.893 version.
So there are two solutions. Or Rstudio changes the way they scale
Rlogo.svg, or Rlogo.svg is correctly scaled during R install. Here is a
Rlogo.svg correctly scaled to replace the original version:

Two different sizes of R logo are shown in Rstudio in the Help at the
package level.
For example, numderiv shows a nice discreet logo located at (in MacosX):
/Library/Frameworks/R.framework/Versions/3.3/Resources/doc/html/logo.jpg
whereas packrat shows a huge logo located at:
/Library/Frameworks/R.framework/Versions/3.3/Resources/doc/html/Rlogo.svg
The choice between both depends on the path indicated in the file
Index.html located in html folder for each package.
It would be better to have svg version of Rlogo.svg of the same size
than logo.jpg (I have converted the Rlogo.svg into the same size than
logo.jpg and it looks much better whit the new version).
What versions are you talking about? I'd guess your packages were
built with different versions of R if they ended up with different
links to the logo.
Why is RStudio relevant here? I don't think RStudio does anything
with the R help files other than to display them in its built-in browser.
