rShape
An R package that enables
R users to read data stored in LONI Ucf files.
R has many packages available from the
CRAN archive.
The
rJava R interface to Java is used.
Running R from a
unix command line.
How to
Installing R onto an SGI Irix system, in a user's home R libraries.
Usage Notes
Status
Unable to compile a version of R that supports Java interface on IRIX computers - 10 Oct 05, cs
The Problem
install process runs *R CMD INSTALL mcgv" - whose values for CFLAGS (-g -O2) cause illegal
intructions in the assember code.
The Solution
Alter the default CFLAGS optimizations to "-g". R compiles, however, it will run more slowly than
with the optimizations enabled.
To test rShape:
require(rshape)
coordinates<-read_UCF_coordinates("ucffilename")
values<-read_UCF_default_attributes_values("ucffilename")
write_UCF_with_coordinates_and_default_attribute_values("outputname", coordinates, values, "original_ucffilename_as_structural_template")
Lessons Learned
- cross platform testing is important
- difficulty goes up when relying on native compiled code.
