## Default S3 method:
daily2annual(x, FUN, na.rm = TRUE, out.fmt = "%Y", ...)
## S3 method for class 'zoo'
daily2annual(x, FUN, na.rm = TRUE, out.fmt = "%Y-%m-%d", ...)
## S3 method for class 'data.frame'
daily2annual(x, FUN, na.rm = TRUE, out.fmt = "%Y", dates=1,
date.fmt = "%Y-%m-%d", out.type = "data.frame", verbose = TRUE, ...)
## S3 method for class 'matrix'
daily2annual(x, FUN, na.rm = TRUE, out.fmt = "%Y", dates=1,
date.fmt = "%Y-%m-%d", out.type = "data.frame", verbose = TRUE, ...)
|
x |
zoo, xts, data.frame or matrix object, with (sub)daily/monthly time series. |
FUN |
Function that have to be applied for aggregating from (sub)daily/monthly into annual time step (e.g., for precipitation |
na.rm |
Logical. Should missing values be removed? |
out.fmt |
Character indicating the date format for the output time series. See |
dates |
numeric, factor or Date object indicating how to obtain the dates for corresponding to each gauging station |
date.fmt |
character indicating the format in which the dates are stored in dates, e.g. %Y-%m-%d. See |
out.type |
Character that defines the desired type of output. Valid values are: |
verbose |
logical; if TRUE, progress messages are printed |
... |
further arguments passed to or from other methods. |

## Ex4: Loading the monthly time series of precipitation within the Ebro River basin
data(EbroPPtsMonthly)
# computing the annual values for the first 10 gauging station in 'EbroPPtsMonthly'
a <- monthly2annual(EbroPPtsMonthly[,1:11], FUN=sum, dates=1)
# same as before, but with a nicer format of years
a <- monthly2annual(EbroPPtsMonthly[,1:11], FUN=sum, dates=1, out.fmt="%Y")
