Rowmedians

WebThe implementation of rowMedians () is optimized for both speed and memory. To avoid coercing to double s (and hence memory allocation), there is a special implementation for integer matrices. That is, if x is an integer matrix, then rowMedians (as.double (x)) would require three times the memory of rowMedians (x), but all this is avoided. WebObtaining colMeans in R uses the colMeans function which has the format of colMeans (dataset), and it returns the mean value of the columns in that data set. The function has several optional parameters that can be added. One of these optional parameters is the logical perimeter na.rm, which determines if the function skips N/A values.

WebIn the cases of having conflicting names, is it not appropriate then to use the "package::function" form for calling a particular function? On Wed, Mar 30, 2016 at 11:14 PM Michael Lawrence … WebChapter 8. Beta diversity. Beta diversity is another name for sample dissimilarity. It quantifies differences in the overall taxonomic composition between two samples. Common indices include Bray-Curtis, Unifrac, Jaccard index, and the Aitchison distance. Each of these (dis)similarity measures emphasizes different aspects.

WebWhile this is working, one can note that we call the same R function rowMedians() in the package Biobase in both Python decorated functions. What is happening is that the dispatch is performed by R. If this is ever becoming a performance issue, the specific R function dispatched can be prefetched and explicitly called in the Python function.
