# `scale` can be set to TRUE. # We will show the differences of scaling and un-scaling effects. pca <- prcomp(data_t[,1:variableL], scale=T) # sdev: standard deviation of the principle components. # Square to get variance # percentVar <- pca$sdev^2 / sum( pca$sdev^2) # ...
objects as outputs. Sometimes, they may modify objects in the environment or cause side effects outside the R environment like plotting graphics, saving files, or sending data over the network. Internal These are object types that are formally defined by R but which aren't normally accessible w...
the solution for the equation of state, which is a matrix differential equation is calculated. to resolve this, two different methods are presented, first using the properties of the matrix functions and by other side, using the classical method...
牛津大学的Rahul Satija等开发的Seurat,最早公布在Nature biotechnology, 2015,文章是; Spatial reconstruction of single-cell gene expression data , 在2017年进行了非常大的改动,所以重新在biorxiv发表了文章在 Integrated analysis of single cell transcriptomic data across conditions, technologies, and species 。

There are many other possibilities that might have fewer side effects. We could return a vector of zeroes or the original input vector, for example. Checks are run on the arguments to the function. In each case, if an error is detected, a default value is returned and a message is ...

There are three facilities for generating uniform pseudo-random numbers in 32-bit integer, single precision floating point, and double precision floating point formats: The functions described in the addrans(3m) manual page are based on a family of table-driven additive random number generators. ...
