Question

I am working on creating some personalized reports using Latex and Sweave. I need to generate the reports in a batch (the dataset has about 300,000+ rows). I have come across several methods on the web for doing this but am looking for suggestions on a simple straightforward method.

The data frame has several rows containing the names of Cars and associated values such as,

Date  CarName    NumSold     NumUnsold     MostPaid  LeastPaid           Model ....
09/04 Honda           10            20        50000      10000          Accord ....
09/06 Audi             5            30       100000      30000              A4 ....
09/05 Honda           12            20        50000      10000          Accord ....
09/06 Honda           18            27        53000      60000          Accord ....
09/08 Toyota          12            20        50000      10000           Camry ....
...

Suppose there are 400 different types of Cars we get from (unique(df$CarName))

I need to create a nice looking LaTeX report for each of these 400 Types of Cars with specific data such as say, LeastPaid for by date, NumSold by Date, by Model etc etc … using table, apply, reshape, etc etc. The individual reports will also contain images

My question is with how to generate the reports in a batch. I can create the Sweave Rnw for a single CarName, but need to create the same for the 399 other Cars also and save them with some unique name like CarName-Date.tex.

Answer 1

You can do this using Sweave or the brew package. I will try to post a short example if I find time, but here are two great resources available that provide very detailed instructions on how to go about it.

1. brew:Creating Repetitive Reports
2. Batch Individual Personality Reports Using R, Sweave and Latex
