What is KLINK?

Forensic kinship testing with linked STR markers, now peer-reviewed and taking data from anywhere.

KLINK is a Shiny application and R package for kinship testing that accounts for linkage between STR markers, rather than treating all markers as independent. The built-in genetic map covers 50 common STR markers, pairs them dynamically after data loads, and lets the user set the maximum distance at which a pair counts as linked. Custom marker maps can now arrive as Excel files including KLINK's own download files, and a paper describing the tool was published in FSI:Genetics in 2026.

What is spsurvey?

spsurvey has spent four years consolidating after its 5.0.0 rewrite rather than adding to it

spsurvey implements design and analysis for spatially balanced environmental survey samples, the GRTS methodology used in large-scale monitoring programs. The 5.0.0 rewrite is the defining event in its history, and everything in this window is aftercare. 5.6.0 in September 2025 finally removed the startup message warning users about that upgrade, several years on.

2.5

Forensic kinship testing with linked STR markers, now peer-reviewed and taking data from anywhere.

◆ Current state

KLINK is a Shiny application and R package for kinship testing that accounts for linkage between STR markers, rather than treating all markers as independent. The built-in genetic map covers 50 common STR markers, pairs them dynamically after data loads, and lets the user set the maximum distance at which a pair counts as linked. Custom marker maps can now arrive as Excel files including KLINK's own download files, and a paper describing the tool was published in FSI:Genetics in 2026.

◆ Where it's heading

The direction is from fixed panel toward general instrument. Hard-coded linkage pairs gave way to dynamic pairing, the built-in map grew from 18 to 50 markers, the map itself was then moved out to the norSTR package, and the app now accepts custom maps in several file formats and decimal conventions. Method capability tracks the upstream pedsuite rather than KLINK itself: special lumping in pedprobr and pedmut is what allowed complex mutation models in common pedigrees, and the newest release pins pedtools 2.11.0 and pedprobr 1.1.0 for faster likelihoods and better handling of looped pedigrees. Much of the remaining work is unglamorous casework ergonomics, replacing stray Norwegian text in Excel output, controlling table heights, fixing karyogram colours.

◆ Prediction

With the map externalised and custom maps loading from multiple formats, the likeliest next step is broader marker-panel coverage through norSTR rather than changes in KLINK itself. Method gains should continue to arrive as pedprobr and pedmut version bumps.

spsurvey has spent four years consolidating after its 5.0.0 rewrite rather than adding to it

◆ Current state

spsurvey implements design and analysis for spatially balanced environmental survey samples, the GRTS methodology used in large-scale monitoring programs. The 5.0.0 rewrite is the defining event in its history, and everything in this window is aftercare. 5.6.0 in September 2025 finally removed the startup message warning users about that upgrade, several years on.

◆ Where it's heading

The direction is toward standard R idioms and away from bespoke ones. 5.4.0 introduced sp_frame and sp_design classes so plot() and summary() work directly, keeping sp_plot() and sp_summary() only for backwards compatibility; 5.5.0 moved warnings from cat() to message() so they can be suppressed normally, and added adjwgtNR() for non-response weight adjustment. Documentation is being pushed off CRAN onto the package website, with only the Start Here vignette remaining. Release cadence is slow — five releases across roughly four years.

◆ Prediction

With the migration messaging retired and the class system settled, further releases are likely to stay in maintenance and statistical-detail territory. Nothing in the entries suggests another rewrite.
