GSEDATA We will first need to download the annotation file for GPL6887. The soft files and matrix files from GEO contain metadata and abundance data about the experiment. I downloaded te soft data and loaded directly on R using the comands on Neil Graham link: gds858 <- getGEO(filename='GDS858.soft.gz') https://www.bioconductor.org/packages/devel/bioc/vignettes/GEOquery/inst/ 30 Apr 2019 We will be using the GEOquery package to get the data files from GEO website Here, we download the data files and import them with getGEO() function: data.matrix <- do.call('cbind', lapply(GEOquery::GSMList(gse.soft),
