Dear All,
I have a data set containing year, month, day and counts as shown below:
data <- read.table("data.txt", col.names = c("year", "month", "day", "counts"))
Using the formula below, I converted the data to as date and plotted.
new.century <- data$year < 70
data$year <- ifelse(new.century, data$year + 2000, data$year + 1900)
data$date <- as.Date(ISOdate(data$year, data$month, data$day))
The form of the data is:
16 1 19 9078
16 1 20 9060
16 1 21 9090
16 1 22 9080
16 1 23 9121
16 1 24 9199
16 1 25 9289
16 1 26 9285
16 1 27 9245
16 1 28 9223
16 1 29 9298
16 1 30 9327
16 1 31 9365
Now, I wish to include time (hour) in my data. The new data is of the form:
05 01 06 14 3849
05 01 06 15 3845
05 01 06 16 3836
05 01 06 17 3847
05 01 06 18 3850
05 01 06 19 3872
05 01 06 20 3849
05 01 06 21 3860
05 01 06 22 3868
05 01 06 23 3853
05 01 07 00 3839
05 01 07 01 3842
05 01 07 02 3843
05 01 07 03 3865
05 01 07 04 3879
05 01 07 05 3876
05 01 07 06 3867
05 01 07 07 3887
I now read the data as:
data <- read.table("data.txt", col.names = c("year", "month", "day",
"counts", "hour")) and also included hour in data$date <-
as.Date(ISOdate(data$year, data$month, data$day))
i.e data$date <- as.Date(ISOdate(data$year, data$month, data$day, data$hour)).
However, these did not work.
Can you please assist be on how to get this date and time in the right
format. The right format I got without hour looks like : 2005-12-29"
"2005-12-29" "2005-12-29" "2005-12-29" "2005-12-29"
[8696] "2005-12-29" "2005-12-29" "2005-12-29" "2005-12-29" "2005-12-29"
[8701] "2005-12-29" "2005-12-29" "2005-12-29" "2005-12-29" "2005-12-29"
[8706] "2005-12-29" "2005-12-29" "2005-12-29" "2005-12-29" "2005-12-29"
I used this in my plot. Please I want this format to include hour.
Many thanks for your help. I am just a newbe. I am not sure if this
forum is the right one. After registration, I tried to post to Nabble
forum where I registered but could not succeed.
If there is a mistake, please help/direct me to the right forum.
Best regards
Ogbos
