The last stable version of the package can \nbe installed from CRAN using:\n\n```{r}\ninstall.packages('PCADSC')\n```\nTo install the development version of PCADSC, run the following commands\nfrom within R:\n```{r}\nlibrary(devtools)\ninstall_github('annennenne/PCADSC')\n```\nThe PCADSC methods are described in our [article manuscript](https://github.com/AnnePetersen1/PCADSC/blob/master/article/PCADSC_manuscript_withFigures.pdf). \n\nThe basic functionality of the package can be inspected using the following lines of code:\n```{r}\nlibrary(PCADSC)\n\n#Load iris data\ndata(iris)\n\n#Define grouping variable, grouping the observations by whether their species is\n#Setosa or not\niris$group \u003c- \"setosa\"\niris$group[iris$Species != \"setosa\"] \u003c- \"non-setosa\"\n\n#Make a PCADSC object, splitting the data by \"group\"\nirisPCADSC \u003c-PCADSC(iris, \"group\", var=setdiff(names(iris), c(\"group\", \"Species\")),\n                    doCE = TRUE, doAngle = TRUE, doChroma = TRUE)\n                         \n#Make a cumulative eigenvalue (CE) plot\nCEPlot(irisPCADSC)\n\n#Make an angle plot \nanglePlot(irisPCADSC)\n\n#Make a chroma plot\nchromaPlot(irisPCADSC)\n```\n\nOur current to-do list for the package is posted below. If you have any further suggestions for added functionality, or have a bug to report, please open an issue and let us know.\n\n**To do**\n- Make `print()` methods for `pcaRes`, `CEInfo`, `angleInfo`, `chromaInfo` and `PCASDC` objects\n- Make `summary()` methods for `pcaRes`, `CEInfo`, `angleInfo`, `chromaInfo` and `PCASDC` object\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fannennenne%2Fpcadsc","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fannennenne%2Fpcadsc","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fannennenne%2Fpcadsc/lists"}
