[R] Printing standard notation and scientific notation in the same column of a dataframe

[David Disabato]

Hi R-help,

I was wondering if it was possible for a column of a dataframe to print
some numbers in standard notation and some in scientific notation. Say my
column of data (i.e., dat$x) has numbers between 0 and 1 with a few numbers
very close to 0. When using the "scipen" argument in "options," R seems to
print all numbers of a column in scientific notation if one number in the
column is a decimal with a starting digit smaller than the "scipen"
argument. It is annoying that is changes ALL numbers in that column to
scientific notation though. For example, I do want .00000000000000000001 in
scientific notation, but I want .52 in standard form. Ideally, an example
dataframe column would print as something like this:

print(dat$x)
.52
.17
.03
1.0e-20

However, I cannot figure out how to do this. Any solutions people are aware
of?
