[R] Manipulating two large dataset differing by date and time

[Ogbos Okike]

Dear Members,

Compliments of the Season!!


Below is a part of a code I use for Fourier analysis of signals. The code
handles data with the format 05 01 01    8628 (year, month, day and count)
                              05 01 02    8589 (year, month, day and count)
The sample data is attached as 2005daily.txt.

I would like to adapt the code to handle data of the form:
05 01 01 00    4009 (year, month, day, hour and count)
05 01 01 01    3969 (year, month, day, hour and count)

The sample is also attached as 2005hourly.txt.

Thank you very much for your kind inputs.

Ogbos




data <- read.table("2005daily.txt", col.names = c("year", "month", "day",
"counts"))

new.century <- data$year < 50

data$year <- ifelse(new.century, data$year + 2000, data$year + 1900)

data$date <- as.Date(ISOdate(data$year, data$month, data$day))
x1 = data$date
 y = data$counts
