Re: [R] Converting daily data series to monthly series
Thanks Gabor,
I have got the idear how to aggregate the daily data into monthly data
using the zoo package. However, as I indicated earlier, in the series I am
analysing, 29th February of leap years are excluded (so as to have 365 days
in each year). How do I coerce(force) the the aggregate command to only
sum 28-days in February for all the years.
Thanks

There is a monthly aggregation of daily data example in the
zoo-quickref vignette:
vignette("zoo-quickref")
and there are also relevant examples using aggregate.zoo or duplicated
in the example section of ?aggregate.zoo

[R] Converting daily data series to monthly series
Hi Users, I have daily series of data from 1962 - 2000, with the data for February 29th in leap years excluded, leaving 365 daily values for each year. I wish to convert the daily series to monthly series. How can I do this using the zoo package or any other package?

[R] Problem writing netcdf data with Rclim
Dear Users:
I am able to read the file precip.nc (CMAP monthly precip) using the Rclim
package. How ever, when I try to write the data in a netcdf file, I get the
following error about the missing value attribute:
> pcpmon<-netcdfread("precip.nc","lon","lat","time","precip",unpack=T)
>
netcdfwrite(pcpmon$lon,pcpmon$lat,pcpmon$data,"pcpmon.nc",pcpmon$time,mv=-99
9)
Error: Found NAs but no missing value attribute
I can't figure out the error in the missing value attribute.
How ca I fix the error?
Thanks

[R] Adjusting X-axis time scale
Dear all, I am plotting daily data from 1950 to 2000 and I wish to have the time in X-axis to indicate years and NOT days (i.e 1950 1951,..,2000 instead of 1,2, 3, ..). How do I set the x-axis to show years instead of days.
