## Compute the GC content of DNA and probe sequences

### Description

Simple auxiliary function to compute the GC content of a given set of DNA sequences, such as microarray probe sequences.

### Usage

    compute.gc(probe.sequences, digits = 2)

### Arguments

`probe.sequences` | character vector of DNA or probe sequences of which the GC content is to be computed
`digits` | integer specifying the desired precision

### Value

a numeric vector with sequence-wise GC contents; the names of this vector are the names of the supplied `probe.sequences`.

### See Also

Function `basecontent` in package `matchprobes` for a more general function to compute base occurrence in sequences

### Examples

      ex.seqs <- c("gattaca", "GGGNTT", "ggAtT", "tata","gcccg")
      names(ex.seqs) <- paste("sequence",1:5,sep="")
      compute.gc(ex.seqs)
