spatial.avg.field

[cyndyfem]

Hi,
I followed the examples on the wiki.
Everything was ok. However, I got to a stage where I should compute anomalies, spatial averaging, convert to station objects, and combine
djfs <- as.station(spatial.avg.field(anomaly(djf)))

It says Error in spatial.avg.field(anomaly(djf)) :
could not find function "spatial.avg.field"

I tried spatial too, same thing.

I tried aggregate.area, it says
Error in X[i, ] <- X[i, ] * aweights2 :
number of items to replace is not a multiple of replacement length

I tried aggregate.field, it says
Error in aggregate.field(anomaly(djf)) :
argument "by" is missing, with no default

esd version: 1.10.7

Please, what am I doing wrong?
Thanks

library(esd)
setwd("V:/ERA5/Daily/")

era40 <- subset(retrieve('era5_sp_daily_mean_regrid.nc',lon=c(-40,40),lat=c(0,25)),it=c(1990,2002))

Era40 <- as.monthly(era40)

ERA40 <- as.4seasons(Era40)
djf <- subset(ERA40,it=1)

djfs <- as.station(spatial.avg.field(anomaly(djf)))

Hi,

I will have a look in all this and come back to you soon.

Bests,

OK. Thanks.
