conditional subset and reorder dataframe rows
...dataframe (~1,200,000 rows deep) and I'd like to conditionally reorder groups of rows in this dataframe.
I would like to reorder any rows where the Chr.Strand column contains a '-' but reorder within subsets delineated by the Probe.Set.Name column.
# toy example ####
library(plyr)
negStrandGene <- data.frame(Probe.Set.Name = rep('ENSMUSG00000022174_at', 6), Chr = rep(14,6), Chr.Strand = rep('-', 6), Chr.From = c(54873546, 54873539, 54873533, 54873529, 54873527, 54873416), Probe.X = c(388,1634,2141,2305,882,960), Probe.Y = c(2112, 1773, 1045, 862, 971, 2160))
