“…Implementations where PCA results can be explored are available, mostly focused on small sample datasets, such as Fisher's iris (Fisher, 1984) (https://gist.github.com/dgrapov/5846650 or https://github.com/dgrapov/DeviumWeb, https://github.com/benmarwick/Interactive_ PCA_Explorer) and have been developed rather for generic data, without considering the aspects typical of transcriptomic data (http://langtest.jp/shiny/pca/, (Vaissie et al, 2017)). In the field of genomics, some tools are already available for performing such operations (Sharov et al, 2005;la Grange et al, 2009;Metsalu and Vilo, 2015;Khomtchouk et al, 2016;Manimaran et al, 2016;Nelson et al, 2016;Schultheis et al, 2018), yet none of them feature an interactive analysis, fully integrated in Bioconductor, while also providing the basis for generating a reproducible analysis (Peng, 2011;McNutt, 2014). Alternatively, more general software suites are also available (e.g.…”
