R的数据结构有6种形态:向量(vector)、矩阵(matrix)、数组(array)、数据框(data frame)、时间序列(time series)、列表(list)。 (1)向量 向量是由若干个基础类型相同的值存储在一起所组成的, 各个元素可以按序号访问。 # 为什么说向量中的元素性质相同呢? x<-c(1,"he") x # [1] "1" "he" typeof(...

To write it, it took three months; to conceive it – three minutes; to collect the data in it – all my life. F. Scott Fitzgerald Introduction sqldf is an R package for runing SQL statements on R data frames, optimized for convenience. The user simply specifies an SQL statement in R ...
Depending on the input parameters, output from theget.multimirfunction is a list with several data frames containing results from a given external database, predicted, validated, and disease and drug components of multiMiR, and a summary (see examples in ‘Results’ section). The result includes...
Its core functions for returning tidy data frames of draws are built on top of posterior::as_draws_df(). Drop-in functions to translate tidy column names used by tidybayes to/from names used by other common packages and functions, including column names used by ggmcmc::ggs (via to_gg...

This parameter is equivalent to calling set.seed(value) in R code. Submit the pipeline. Results Execute R Script components can return multiple outputs, but they must be provided as R data frames. The designer automatically converts data frames to datasets for compatibility with other components....
