readData: Reading of Disease Data

In jimhester/surveillance: Temporal and Spatio-Temporal Modeling and Monitoring of Epidemic Phenomena

Description

Reading of disease data. In the package disease data are saved in a file <abb>.txt containing three columns – the weeknumber (week), the observed number of counts (observed) and a state (state). The data are read using read.table(...,header=T), hence the file has to contain a header.

Usage

    readData(abb,week53to52=TRUE,sysPath=TRUE)

Arguments

abb	abbreviation of the diseasename.
week53to52	Boolean indicating whether to convert RKI 53 Weeks System to 52 weeks a year
sysPath	Boolean, if TRUE then R automatically looks in the data directory of the surveillance package.

Details

This function is only kept for backwards compability. As of 0.9-2 all data should be read with data.

Value

disProg

a object disProg (disease progress) including a list of the observed and the state chain.

Examples

    readData("m5")

    #To bring a single vector of counts into a format, which can be
    #handled by readData. Assume ``counts'' is a vector of counts.
    counts <- rpois(100,20)
    counts <- data.frame("week"=1:length(counts),"observed"=counts,
                         "state"=rep(0,length(counts)))
    write(c("week","observed","state"),file="disease.txt",ncol=3)
    write(t(as.matrix(counts)),file="disease.txt",ncol=3,append=TRUE)
    disease <- readData("disease",week53to52=FALSE,sysPath=FALSE)
