Until recently, existing PC algorithm implementations in R had important limitations regarding missing values, temporal structure or mixed measurement scales (categorical/continuous), which are all common features of cohort data. The new R packages presented here, micd and tpc, fill these gaps.</p><p><strong>Implementation: </strong>micd and tpc packages are R packages.</p><p><strong>General features: </strong>The micd package provides add-on functionality for dealing with missing values to the existing pcalg R package, including methods for multiple imputations relying on the Missing At Random assumption. Also, micd allows for mixed measurement scales assuming conditional Gaussianity. The tpc package efficiently exploits temporal information in a way that results in a more informative output that is less prone to statistical errors.</p><p><strong>Availability: </strong>The tpc and micd packages are freely available on the Comprehensive R Archive Network (CRAN).
