|
|
|
36 * R packages
|
|
|
37 + **batch** from CRAN
|
|
|
38
|
|
|
39 ```r

|
|
40 install.packages("batch", dep=TRUE)
|
|
|
41 ```
|
|
|
42
|
|
|
43 + **ade4** from CRAN
|
|
|

|
46 install.packages("ade4", dep=TRUE)
|
|
|
47 ```
|
|
|
48
|
|
|
49 + **pcaMethods** from Bioconductor
|
|
|
50
|
|
|
51 ```r
|
|
|
52 source("http://www.bioconductor.org/biocLite.R")
|
|
|
53 biocLite("pcaMethods")

61 ```
|
|
|
62
|
|
|
63 ### Tests
|
|
|
64
|
|
|
65 The code in the batch_correction_wrapper can be tested by running the `runit/batchcorrection_runtests.R` R file
|
|
|
66
|
|
|
67 You will need to install **RUnit** package in order to make it run:
|
|
|
68 ```r
|
|
|
69 install.packages('RUnit', dependencies = TRUE)
|
|
|
70 ```
|
|
|
71
|
