چکیده
Digital terrain models (DTMs) are datasets containing altitude values above or below a reference level, such as ellipsoid tidal datum over geographic space, often in the form of regularly gridded raster. They can be used to calculate attributes that describe shape and characteristics topographic surfaces. Calculating these requires multiple software packages expensive specialized. We have created free, open-source R package, MultiscaleDTM, allows for calculation members from each five major thematic groups attributes: slope, aspect, curvature, relative position, roughness, DTM. Furthermore, calculated at spatial scales analysis, key feature is missing many other packages. Here, we demonstrate functionality package provide simulation exploring relationship between slope roughness. When roughness measures do not account exhibit strong positive correlation. To minimize this correlation, propose new measure called adjusted standard deviation. In most scenarios tested, produced lowest rank correlation with out all tested. Lastly, shows some existing literature supposed independent actually inverse cases.

An R package for state-trace analysis.
State-trace analysis (Bamber, Journal of Mathematical Psychology, 19, 137-181, 1979) is a graphical analysis that can determine whether one or more than one latent variable mediates an apparent dissociation between the effects of two experimental manipulations. State-trace analysis makes only ordinal assumptions and so, is not confounded by range effects that plague alternative methods, especia...
متن کاملchangepoint: An R Package for Changepoint Analysis
One of the key challenges in changepoint analysis is the ability to detect multiple changes within a given time series or sequence. The changepoint package has been developed to provide users with a choice of multiple changepoint search methods to use in conjunction with a given changepoint method and in particular provides an implementation of the recently proposed PELT algorithm. This article...
متن کاملOntologyTraverser: an R package for GO analysis
UNLABELLED Gene Ontology (GO) annotations have become a major tool for analysis of genome-scale experiments. We have created OntologyTraverser--an R package for GO analysis of gene lists. Our system is a major advance over previous work because (1) the system can be installed as an R package, (2) the system uses Java to instantiate the GO structure and the SJava system to integrate R and Java a...
