Hi,
I would like to read values from an ASCII text file that contains
information in the following format:
DEVICE = 'PC'
CPU_SPEED = '1999', '233'
...
It's like a config file.
How can I e.g. get R to read the 2nd value of CPU_SPEED?
How do I go through text files and search for keywords and

Read in data using readLines and replace
= with comma and delete all spaces.
Then reread using read.table and set the
rownames to column 1 removing column 1.
# test data
Lines0 - DEVICE = 'PC'
CPU_SPEED = '1999', '233'
# if reading from a file then
# replace next line with something like Lines
Something like this?
library(Hmisc)
t - readLines(clipboard)
t
[1] DEVICE = 'PC' CPU_SPEED = '1999', '233'
ix - grep(CPU_SPEED,t)
loc - substring.location(t[ix],,)
cpu - substring(t[ix],loc$first+2)
cpu
[1] '233'

Here is one more solution using the same Lines0 from last time.
This one uses strapply from gsubfn to pick out all the fields in
each line creating a list named by the keywords (rather than
a data frame as in the previous solution). The names of the
components are the keywords so we remove them
Here is a slight simplification of this one using row.names= in
the read.table to avoid the subsequent manipulations. We
use Lines0 defined in the earlier post:
# replace next line with something like Lines - readLines(myfile.dat)
Lines - readLines(textConnection(Lines0))
Lines - gsub(=, ,,
