To create a Date object from a simple character string in R, you can use the as.Date() function. The character string has to obey a format that can be defined using a set of symbols (the examples correspond to 13 January, 1982): %Y: 4-digit year (1982) %y: 2-digit year (82) ...

与normalizeBetweenArrays用于组内矫正不同,limma包的removeBatchEffect可以用于多个数据集的批次矫正。 数据要求:numeric matrix, or any data object that can be processed by getEAWP containinglog-expression valuesfor a series of samples. Rows correspond to probes and columns to samples. library(limma) mode...
store categorical(绝对) variables. The difference between a categorical variable and a continuous(连续) variable is that a categorical variable can belong to alimited number of categories(类别). A continuous variable, on the other hand, can correspond(符合) to an infinite(无限) number of values...
Positive values correspond to individuals that “died too soon” compared to expected survival times. Negative values correspond to individual that “lived too long”. Very large or small values are outliers, which are poorly predicted by the model. ...
Notice that the elements of the resulting vector that correspond with the NA values in x are also NA. To make things a little more interesting, lets create a vector containing 1000 draws from a standard normal distribution with y <- rnorm(1000). ...
from the reverse side, i.e., the last (or rightmost) of identical elements would correspond to...
For example, we may only be interested in the first 20 elements of a vector, or only the elements that are not NA, or only those that are positive or correspond to a specific variable of interest. By the end of this lesson, you'll know how to handle each of these scenarios. ...
The “lexical” in lexical scoping doesn't correspond to the usual English definition (“of or relating to words or the vocabulary of a language as distinguished from its grammar and construction”) but comes from the computer science term “lexing”, which is part of the process that convert...
