Dear all,
My name is Maria Lathouri and I am currently doing a PhD at Imperial College of
London about time series of environmental variables in surface waters. I am
trying to do some time plots with R but it seems that it is not working.
The problem is that the time is not regular, for example, a small dataset can
be seen below:
Date pH
1/02/1998 5.5
5/03/1998 5
8/12/1998 6
1/02/1999 6.1
...
08/10/2000 7.2
I have used the function >plot(DATE, pH) and then >lines(pH), but the line does
not join the points. I have used many combinations, e.g. >plot(DATE, pH) and
then >lines(DATE, pH), where I get a plot with full of lines inside or just
>plot(pH) and then >lines(pH) where the line connects the points but in x-axis
I do not have the DATE. It says Index from 0 to 80.
Do you know if there is a function where I can have in x-axis the DATE
(irregular dates) and in y-axis the variable with a continuous line, showing
how it changes through time?
I know that your time is valuable but I would appreciate it if you could help
me.
Thank you very much in advance for your time and help.
I am looking forward to hearing from you.
Sincerely yours
Lathouri Maria
