The gDRtestData package is intended to store and generate example data that can be used through the gDR suite.
Since gDR is a computational suite for drug response data from any experiment, a synthetic dataset is also needed for testing and exploration.
The basis of this package are two functions to generate the synthetic sets of cell lines and drugs.
cell_lines <- create_synthetic_cell_lines()
drugs <- create_synthetic_drugs()These base objects can be extended with additional information.
cl_rep <- add_data_replicates(cell_lines)
head(cl_rep)cl_conc <- add_concentration(cell_lines)
head(cl_conc)Or the user can do both with one function:
df_layout <- prepareData(cell_lines, drugs)
head(df_layout)Additionally, the user may fill in the full response data with the day 0 part.
df_layout_small <- prepareData(cell_lines[seq_len(2), ], drugs[seq_len(4), ])
df_layout_small$Duration <- 72
df_layout_small$ReadoutValue <- 0
df_layout_small_with_Day0 <- add_day0_data(df_layout_small)
head(df_layout_small_with_Day0)In a further step, the user may generate a set of synthetic results:
hill <- generate_hill_coef(cell_lines, drugs) ec50_met <- generate_ec50(cell_lines, drugs) einf_met <- generate_e_inf(cell_lines, drugs)Or the user can create full response data with one function (for single-agent):
response_data <- prepareMergedData(cell_lines, drugs)
head(response_data)SUMMARY
| Step | Function | Output (data.table) |
|---|---|---|
| 0 | create_synthetic_cell_lines() | synthetic cell lines |
| 0 | create_synthetic_drugs() | synthetic drugs |
| 1 | prepareData() | cell lines and drug merged with replicates and concentration |
| 2 | prepareMergedData() | full response data for single-agent |
| 2 | prepareComboMergedData() | full response data for combo |
| 2 | prepareCodilutionData () | full response data for co-dilution |
The gDR data model is built on the MultiAssayExperiments (MAE) structure. A detailed description of the gDR data model can be found in gDRcore package vignette.
In inst/testdata the user may find a set of qs files that are examples of gDR data model for different data types. In the file synthetic_list.yml one can find a list of these datasets. Currently available are:
#> * combo_2dose_nonoise,
#> * combo_2dose_nonoise2,
#> * combo_2dose_nonoise3,
#> * combo_codilution_small,
#> * combo_codilution,
#> * combo_matrix_small,
#> * combo_matrix,
#> * combo_triple,
#> * medium,
#> * small_no_noise,
#> * small,
#> * wLigand .The script generate_example_data.R which shows how to generate and process above-mentioned datasets is in inst/scripts dir.
All key functions can be found in package gDRcore in script generate_wrappers.R.
In inst/annotation_data the user can find CSV files used in gDRcore for testing annotation functions.
Other files which were not mentioned above are used for testing gDR suite functionality.
