Part of R Language Collective 2 I am trying to write a loop in R to collapse rows. Let's say I'm using a data frame like this one: r1 <- c(1, 1,1000,2) r2 <- c(1, 1001,2000, 2) r3 <- c(1, 2001,3000, 2) r4 <- c(1, 3001,4000, 1) r5 <-...

也可以在 rmarkdown 中插入代码块，并将代码运行结果输出在 markdown 里。
In the present work, we have created an R function, collapseRows, that implements a host of widely used collapsing methods. We will describe this function in more detail and present several motivating examples involving gene expression data (mRNA abundances). We explore this function in the conte...
Hi! I'mMauricio Caceres; I made gtools after some of my Stata jobs were taking literally days to run because of repeat calls toegen,collapse, and similar on data with over 100M rows. Feedback and comments are welcome! I hope you find this package as useful as I do. ...

There are currently 4 methods for balancing (up-/downsampling) on ID level in balance(). ID method: n_ids Balances on ID level only. It makes sure there are the same number of IDs in each category. This might lead to a different number of rows between categories. ID method: n_rows...
Results We introduce the R function collapseRows that implements several collapsing methods and evaluate its performance in three applications. First, we study a crucial step of the meta-analysis of microarray data: the merging of independent gene expression data sets, which may have been measured ...

Around 1881 CE, herring were being harvested on a large scale in Burrard Inlet, although exact volumes are unknown, and rendered into oil used for lubricating skid rows in forestry (Armitage, 2001:93; Carrothers, 1941:109; Matthews, 1933:133). A floating oil processing vessel, called Spratt...
