if condition and for cycles
I have two questions about R:
1) Does anyone knows why I get the plots but not the summary results of the
linear fitting when I run this code? When I run it outside the if condition
it works fine.
if (op==4) {
t=1:length(time(SeaIce))
fitlinear=lm(SeaIce~t)
windows()
plot.ts(SeaIce)
lines(ts(fitlinear$fitted.values,start=1979,frequency=12))
summary(fitlinear)
fitlinear=ts(fitlinear$fitted.values,start=1979,frequency=12)
c=cos(2*pi*t/12)
s=sin(2*pi*t/12)
fittotal=lm(SeaIce~t+c+s)
summary(fittotal)

Unexpected parameter problem using rsaga.geoprocessor() {RSAGA}
...en, I wrote the following command for importing a grid of binary raw
data while specifying the parameters I usually enter under SAGA:
> rsaga.geoprocessor("io_grid", 4, list(GRID="199710.sgrd",
FILE_DATA="C:/Documents and Settings/lescroel/Mes
documents/pub/DATASETS/seaice/polar-stereo/nasateam/final-gsfc/south/monthly/nt_199710_f13_v01_s.bin",
NX=316, NY=332, DXY=25, XMIN=-3950, DATA_OFFSET=300, TOPDOWN=1))

Using zoo() to aggregate daily data to monthly means
...ns for a daily data series using zoo(). I have
found an odd problem, that seems to be caused by zoo()'s handling of leap
years.
Here's my R script with 2 methods (freq=365, 366) for aggregating the daily
data to monthly series:
library(zoo)
J_link <- "http://www.ijis.iarc.uaf.edu/seaice/extent/plot.csv"
JAXA_data <- read.table(J_link,
skip = 0, sep = ",", dec=".",
row.names = NULL, header = FALSE,
as.is = T, colClasses = rep("numeric",4),
comment.char = "#", na.strings = c("*&...
