An example including all the steps to download a record from Physionet and load its content and the Apnea annotations is included below:
dirorig <- "http://www.physionet.org/physiobank/database/apnea-ecg/"
files <- c("a01.hea", "a01.apn", "a01.qrs")
filesorig <- paste(dirorig, files, sep = "")
for (i in 1:length(files))
download.file(filesorig[i], files[i])
hrv.data <- CreateHRVData()
hrv.data <- LoadBeatWFDB(hrv.data, "a01")
hrv.data <- LoadApneaWFDB(hrv.data, "a01")
