I have a csv file,
heartrate excercise medicine Time
12 0 0 4:30 am
23 5 0 5:00 am
34 6 0 5:30 am
56 3 0 6:00 am
24 12 1 6:30 am
35 2 0 7:00 am
26 5 0 7:30 am
63 4 0 8:00 am
24 3 1 8:30 am
45 9 0 9:00 am
I did the folllowing:
x <- read.table("heart.csv",sep=",")
names(x) <- c("heartrate","ex","Med","Time")
x.newtime <- strptime(x$Time, format= "%H:%M %p")
What I am tring to do is:
First I am trying to get all the data from when there was a medicine taken in previous
hour.
Second I will plot heartrate VS median Excercise in previous hour.
In the first problem, how can I get the desired data? after I got it, should I put it
in a new file? How?
How can I refer to a specific cell in a csv file?
I appreciate your kindly help!
