Error in xCellAnalyisis: Argument 'useNames' must be either TRUE or FALSE in rowVars

[km-2021]

Hello,

When I ran the following code:

packageVersion("xCell")
[1] "1.1.0"
xCellAnalysis(df) -> a
[1] "Num. of genes: 10767"
rowVars(x, rows = rows, cols = cols, na.rm = na.rm, refine = refine, error:
Argument 'useNames' must be either TRUE or FALSE

I get the above error related to the useName argument in the rowVars function.
This error did not occur a few month ago using the same code and data.
Could you please advise how to fix this?

Thank you!

Hi,

I strongly advise using xCell 2.0 instead of this version - https://www.bioconductor.org/packages/release/bioc/html/xCell2.html, now published in Genome Biology: https://link.springer.com/article/10.1186/s13059-025-03784-3

Best,
