data smoothing:

loess(), runmed()

track <- import("foo.wig")

scores <- score(track)

chr1 <- trackchr1 # limit to single chromosome

y <- rep(score(chr1), width(chr1))

x <- as.integer(unlist(ranges(chr1)))

lo <- loess(y ~ x)

GeneAnswers

Problem: Bioconductor 2.6 version doesn't work with yeast. After upgrading R to 2.13 and GeneAnswers to bioconductor 2.8 Error message while loading library: libcdt-4.dll not found.

Solution: Install Graphviz, then add the location of the libcdt-4.dll to your windows path. For Windows XP, My Computer -> Properties -> Advanced -> Environmental Variables button -> Edit. Append a semicolon and the directory with the dll (on my system: C:\Program Files\Graphviz2.20\bin).
