[Bioc-devel] Numeric Operation on DataFrame

[Dario Strbenac]

Good day,

Would it be useful to provide the same operations which can be done to a data.frame for a DataFrame in a future release of S4Vectors? For example,

dataTable <- data.frame(aFeature = 1:5, anotherFeature = 5:1)
colMeans(dataTable)
#  aFeature anotherFeature 
#         3              3
dataTableS4 <- DataFrame(aFeature = 1:5, anotherFeature = 5:1)
colMeans(dataTableS4)
    Error in colMeans(dataTableS4) : 
        'x' must be an array of at least two dimensions
