A shorter tour of R/qtl

چکیده

4. The best way to get help on the functions and data sets in R (and in R/qtl) is via the html version of the help files. One way to get access to this is to type help.start() This should open a browser with the main help menu. If you then click on Packages→ qtl, you can see all of the available functions and datasets in R/qtl. For example, look at the help file for the function read.cross. An alternative method to view this help file is to type one of the following: help(read.cross) ?read.cross The html version of the help files are somewhat easier to read, and allow use of hotlinks between different functions.

Two new heuristic algorithms for Covering Tour Problem

Covering Tour Problem (CTP) is the generalized form of Traveling Salesman Problem (TSP), which has found different applications in the designing of distribution networks, disaster relief, and transportation routing. The purpose of this problem is to determine the Hamiltoniancyclewiththe lowest costusinga subset of all the nodes, such that the other nodes would be in a distance shorter than the ...

A brief tour of R/qtl

R/qtl is an extensible, interactive environment for mapping quantitative trait loci (QTLs) in experimental crosses. It is implemented as an add-on package for the freely available and widely used statistical language/software R (see www.r-project.org). The development of this software as an add-on to R allows us to take advantage of the basic mathematical and statistical functions, and powerful...

Comparison of two QTL mapping approaches based on Bayesian inference using high-dense SNPs markers

To compare different QTL mapping methods, a population with genotypic and phenotypic data was simulated. In Bayesian approach, all information of markers can be used along with combination of distributions of SNP markers. It is assumed that most of the markers (95%) have minor effects and a few numbers of markers (5%) exert major effects. The simulated population included a basic population of ...

A Comparison of the Sensitivity of the BayesC and Genomic Best Linear Unbiased Prediction(GBLUP) Methods of Estimating Genomic Breeding Values under Different Quantitative Trait Locus(QTL) Model Assumptions

The objective of this study was to compare the accuracy of estimating and predicting breeding values using two diverse approaches, GBLUP and BayesC, using simulated data under different quantitative trait locus(QTL) effect distributions. Data were simulated with three different distributions for the QTL effect which were uniform, normal and gamma (1.66, 0.4). The number of QTL was assumed to be...
