isocounts: Sample Count Data
In HegemanLab/ProteinTurnover: Protein Turnover Experiment Analysis

A sample of the kind of count data used by this package.

A data frame with 1224 observations on the following 4 variables.

TimePoint: Day the observation was made on
Channel: Channel the observation was on (that is, how many “heavy” elements there were)
RT: Retention time the observation was made at
Count: Number of items observed

Count data like this can be converted to relative abundances using relAbFromCounts.

data(isocounts)
head(isocounts)
counts <- within(isocounts,{
  Channel <- factor(Channel)
  TimePoint <- factor(TimePoint)
  logCount <- log10(Count)
})
coplot(logCount~RT|Channel*TimePoint, data=counts, show.given=FALSE)
