BA.plot: An R function for Bland-Altman analysis

A Bland–Altman plot (difference plot) in analytical chemistry or biomedicine is a method of data plotting used in analyzing the agreement between two different assays. It is identical to a Tukey mean-difference plot, the name by which it is known in other fields, but was popularised in medical statistics by J. Martin Bland and Douglas G. Altman. WebWe used Bland-Altman plots on the normalized miRNA count distribution to visualize the agreement between results in the EBC and plasma samples with each of the 2 sequencing platforms. 29 Briefly, we set the paired difference between the log 2 count in the plasma and the log 2 count in the EBC of each individual miRNA detected in the y-axis and ...
