workflowr checks: (Click a bullet for more information)

  • ✔ R Markdown file: up-to-date

    Great! Since the R Markdown file has been committed to the Git repository, you know the exact version of the code that produced these results.

  • ✔ Environment: empty

    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 it’s best to always run the code in an empty environment.

  • ✔ Seed: set.seed(20190115)

    The command set.seed(20190115) 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.

  • ✔ Session information: recorded

    Great job! Recording the operating system, R version, and package versions is critical for reproducibility.

  • ✔ Repository version: eba12aa

    Great! You are using Git for version control. Tracking code development and connecting the code version to the results is critical for reproducibility. The version displayed above was the version of the Git repository at the time these results were generated.

    Note that you need to be careful to ensure that all relevant files for the analysis have been committed to Git prior to generating the results (you can use wflow_publish or wflow_git_commit). workflowr only checks the R Markdown file, but you know if there are other scripts or data files that it depends on. Below is the status of the Git repository when the results were generated:

This is the reuslt from susie_bhat using in-sample R:

fit_in = susie_bhat(ss$sumstats$bhat, ss$sumstats$shat, R = r.in, n = 287, L=5, estimate_residual_variance=TRUE)
susie_plot(fit_in, y='PIP', b = data$meta$true_coef)

Using out-sample R, the estimated residual variance becomes negative.

fit_out = susie_bhat(ss$sumstats$bhat, ss$sumstats$shat, R = r.out, n = 287, L=5, estimate_residual_variance=TRUE, check_input=TRUE)
r.in.sub = r.in[226:306, 226:306]
r.out.sub = r.out[226:306, 226:306]
row.names(r.in.sub) = row.names(r.out.sub) = colnames(r.in.sub) = colnames(r.out.sub) = 226:306
color.names = rep('black', nrow(r.in.sub))
color.names[41] = 'red'
