This reproducible R Markdown analysis was created with workflowr (version 1.7.0). The Checks tab describes the reproducibility checks that were applied when the results were created. The Past versions tab lists the development history.
Great job! The global environment was empty. Objects defined in the global environment can affect the analysis in your R Markdown file in unknown ways. For reproduciblity itโs best to always run the code in an empty environment.
The command set.seed(20221103)
was run prior to running
the code in the R Markdown file. Setting a seed ensures that any results
that rely on randomness, e.g. subsampling or permutations, are
reproducible.
Great job! Recording the operating system, R version, and package versions is critical for reproducibility.
To ensure reproducibility of the results, delete the cache directory
Focused_analysis_RUN5_vst_ProteinOnly_cache
and re-run the
analysis. To have workflowr automatically delete the cache directory
prior to building the file, set delete_cache = TRUE
when
running wflow_build()
or wflow_publish()
.
Great job! Using relative paths to the files within your workflowr project makes it easier to run your code on other machines.
Tracking code development and connecting the code version to the
results is critical for reproducibility. To start using Git, open the
Terminal and type git init
in your project directory.
This project is not being versioned with Git. To obtain the full
reproducibility benefits of using workflowr, please see
?wflow_start

Since Brigatinib and Dasatinib has synergistic effect on cell survival, this part is to detect the synergistic effect also on protein expression level. In statistical term, this is an interaction effect, where the effect of two variables is beyond symbol linear additive effect.
