Thank you, any further ideas how to transform the result into a matrix,
something that R easily could search and find values, i want to use the
imported data in various calculations (Rmetrics) and hope to automate the
process somewhat.
Another thing, the htmlTreeParse takes a while to complete, for a 15 row
table it takes about 10-15 seconds, considering i am planning to use this
method on multiple (15-20) tables with up to 1000 rows it might not be the
ideal solution?
