Ah! I forgot to mention that it is possible to call awk from R:
a - system(awk -F'=' '/\\[/{a=$1;next}{print $1,$2,a}' example.ini,
intern=T)
z - textConnection(a)
read.table(z)

var1=value1, A=value3 is almost pure R code.
Is it possible to use this feature to solve the problem?
Along the same lines: you may write a short script that converts the ini
file into R code that can be sourced.
From your example, you can generate the following R code:
Section1 - list()
)
It's sufficiently readable, but using something besides R is not sporty. ;)

.Ini files are, for lack of a better description, ancient.
In this case a device is creating the INI files as part of an experiment, so
the file format cannot be changed (at least easily).
I've looked at XML files from time to time

I need to process some datasets where the configuration information was
stored in .INI-like files, i.e., text files with sections like this:
[Section1]
var1=value1
var2=value2
[Section2]
A=value3
B=value4
...
From Google and other searches I haven't found any package, or function
within a

Here is some code. It replaces [ and ] with = sign and reads the result
into a data frame, DF. DF2 is similar except the section is now in V3.
DF3 is like like DF2 except sections are carried forward and finally
we remove the rows which only had sections.
Lines.raw - [Section1]
var1=value1
In thinking about this a bit more here is an even shorter solution where
Lines.raw is as before:
# Lines - readLines(myfile.ini)
Lines - readLines(textConnection(Lines.raw))
Lines2 - chartr([], ==, Lines)
DF - read.table(textConnection(Lines2), as.is = TRUE, sep = =, fill = TRUE)
L - DF$V1 ==
Here is yet another simplification. This one uses na.locf from the zoo
package to shorten it further and also make it easier to understand.
Below we have one line to read in the .ini file, one line to transform the
characters [ and ] to = and =, the read.table line parses the result and
the next
14 matches
