Scratch pad

• A flow diagram for analysis
• Recap of cDNA microarrays (slide 3)
• Microarray data issues (slide 4)
• Microarray data issues (continued)
  • Large amount of data (GPR/JPEG file size)
  • Subjective
  • Need a log of what was done so someone else can quickly reroduce the results
  • → Reproducible research (someone else can understand/reproduce the results) (McGintys talk)
• Analysis process

• R resources/contributed guides (including downloading)
• R tutorial of basics (objects/indexing/functions)
