read.GLCdata {Rglimclim} | R Documentation |
To read a daily data file of response variables in
Rglimclim
format (see the help for the data.file
argument of the GLCfit
routine). This can also be used
to read daily output files from simulations produced by
GLCsim
.
read.GLCdata(file, missval = -99.99)
file |
Character string giving the name of the data file |
missval |
The number used to denote missing values in the data file |
Although Rglimclim
data files are in fixed-width format,
the use of read.fwf
to read them can be extremely
slow. The present command is much faster.
The function returns a data frame, with named columns
Year
, Month
, Day
, Site
and
Var1
to VarN
, where N
is the number of
variables present in file
. Values of missval
will be replaced with NA
.
Daily weather datasets can be extremely large. Indiscriminate use of this routine may cause slow running or memory problems, therefore.
