cellGeometry 0.6.2 (2026-03-19)

26/02/2026

• Improved error checks in deconvolute() to help with issue #20.

New features

• Add measurement of bias and variance to tune_deconv().
• Add plot_tunevar() to compare MSE, bias^2 and variance.
• Add S3 method for kappa() to compute the condition number of the spillover matrix.
• Add plot_path() to show how the coefficient paths vary with compensation for either a single bulk sample or a cell subclass.
• Add plot_pred() as an alternative to plot_set() for viewing predicted vs observed results from simulations in a single correlation plot.
• Add zero_fraction argument to generate_samples().

cellGeometry 0.6.1

13/01/2026

• Fix subtle division by near 0 issue in nest_output

New features

• Massive speed up of deconvolute().
• Add ridge parameter lambda to deconvolute() [experimental].
• Add resvar metric to tune_deconv() to examine residual variance of bulk gene expression.

Important change

• deconvolute() no longer returns se and hat in the subclass list element. Standard errors can be obtained with the new function se().
• cores argument has been removed from deconvolute()

Important bugfix

• R 4.5.2 for macOS arm64 (Apple M* Macs) has switched to using a faster BLAS (vecLib?) by default, which causes errors with parallelisation in mclapply(). The problem is isolated to R 4.5.2 arm64 for macOS on M* Macs; or any version of R for macOS including intel, if vecLib BLAS is being used via a symlink. The solution is to use cores = 1 with deconvolute() and tune_deconv() whenever vecLib BLAS is in use.
• Removed use of pbmcapply::pbmclapply() as this caused problems with R 4.5.2 for macOS arm64 (Apple M* Macs) even with cores=1. This fixes indefinite hanging in tune_deconv() associated with vecLib BLAS.
