Building on the question how to replace NA with 0.
My data set below has date, station 1, flags for station 1, station 2, flags
for station 2, etc...
I would like to make the values in the station columns equal to 1 and the NA
in the station columns equal to 0 and then sum each row for the numbe
WORKS!!
Thank you for all your help!
plot (
decade[['date']],
decade[['value']],
type = 'l',
col = 'lightsteelblue4',
ylab = 'Discharge [cms]',
main = sprintf('%s [%s]', stn[['metadata']][['name']],
stn[['metadata']][['id']]),
sub = sprintf('Seasonal station with natural
This code WORKS but i can not get it to work when i add the rest of
the sub-title. I have tried three different ways.
# WORKS
plot (
decade[['date']],
decade[['value']],
type = 'l',
col = 'lightsteelblue4',
ylab = 'Discharge [cms]',
main = sprintf('%s [%s]', stn[['metadata']
could it be that the values accessed in the database are not integers or
numeric???

Good one!! Although i think it is stn - none the less neither works.

I'd need access to the whole data file. I tried exporting some data from
the website for it but it got too complex for me! (oh right you need the
HYDAT package - sorry about that) =)
However, it seems to me you have two chunks of data: you got it!!!
stn[flow] - which has daily flow data in
library(RODBC)
library(HYDAT)
You will need to install HYDAT (the zip file) from
http://www.geog.ubc.ca/~rdmoore/Rcode.htm
Below is my current code - which works. The [[]] is the way i am accessing
the columns from the data frame.
thanks again for all your help
# load HYDAT data

I receive the error message below - but i agree with you it should work?
In fact i don't care if it rounds it can just cut the number at 4 decimal
places.
Error: unexpected symbol in:
" sub = sprintf('Seasonal station with natural streamflow - Lat: %s Lon: %s
Gross Area %s km\UB2 - Effective
I am in Canada and it worked!! as:\some text\UB2
the round did not work. i also tried nsmall - to specify number of digits
to the right to the decimal to no avail. i will keep trying and post if
something does work.

I tried you
I am new to the world of R/programming so this may be a really easy question.
I thank you for your patience and help in advance
I would like the characters km^2 to be displayed on the plot subtitle as km
squared - two as a superscript.
I would also like to have the numbers from the data set fo
11 matches
