I'm not being able to export Landsat8 (16bit: 0-65535) TIF to IDRISI .RST
files with writeRaster().
IDRISI (Taiga) fail to read .RST files resulting from writeRaster().
First thing, which may be a typing error from raster help, is that from
?dataType one can read that INT2U range is 0-65534 and
Hi folks!
I have been having significant difficulty using the sp classes to perform
the ENFA in R.
The objective of this posting is to inquire about how to prepare data for
the ENFA, which in previous versions of the software package adehabitat was
carried out via 'data2enfa' and the 'dudi.pca'
Dear Alannie,
Obviously all these datas are confusing :)
The 'enfa' example uses a dataset call 'lynxjura' (not 'data'), which is a
list with several elements. One of these elements is the maps, with the
name 'map' (singular!). This is what you want to achieve. This is simply a
Dear Mathieu,
Thank you for the assistance.
Upon executing the situation where I take the material of 'join' to
replace 'map' I receive an error:
join- cbind(bio1@data, bio2@data, bio3@data, bio4@data, bio5@data,
bio6@data, bio7@data)
tab - slot(join, data)
Error in slot(join, data) :
no
Sorry I didn't spot that one before... Please try:
join- cbind(bio1, bio2, bio3, bio4, bio5, bio6, bio7)
and check the class and data:
summary(join)
You want this to be of class SpatialGridDataFrame (or
SpatialPixelsDataFrame), so you want to keep the spatial attributes
together with the
Dear Mathieu,
The join/cbind/@data is wonderful!
However, if I try to join the location data as a data.frame or sp class it
does not work.
What would be the solution to this portion of the equation?
In other words, how to I add locations to the formula?
Thank you a million * ∞ !
Alannie
Not sure where your problem is. If you have the SpatialPixelsDataFrame and
the SpatialPoints, did you try to go on like in the example?
tab - slot(map, data)
pr - slot(count.points(locs, map), data)[,1]
pc - dudi.pca(tab, scannf = FALSE)
(enfa1 - enfa(pc, pr, scannf = FALSE, nf = 3))
etc.,
Greetings, R helpers,
I have been using the Tps() function in the fields package to model
response surfaces for some residuals data.
But i don´t know how i can get more resolution and fill all the shape area?
I hope someone can help me.
Thank you,

Hello Geo-Rs!
I'm using the latest version of gstat and spacetime. I'm trying to fit a
variogramST, but I get the following:
city1b.st -
STFDF(sp=tempb,time=liltime,data=data.frame(index=city1b.df$index))
str(city1b.st)
Formal class 'STFDF' [package spacetime] with 4 slots
