Error: as(, "dgeMatrix") is deprecated since Matrix 1.5-0; do as(as(as(., "dMatrix"), "generalMatrix"), "unpackedMatrix") instead

I got the same error, for everyone who encounters this problem afterward, the solution is pretty straightforward, just downgrade Matrix to 1.4.1 by:

install.packages("https://cran.r-project.org/src/contrib/Archive/Matrix/Matrix_1.4-1.tar.gz", repos=NULL, type="source")

However, my Seurat version is 4.1.1 and requires Matrix >= 1.5.0, so the package needs to be upgraded after I run scMetabolism... I suppose it's possible to download the source code and change as(, "dgeMatrix") to as(as(as(., "dMatrix"), "generalMatrix"), "unpackedMatrix") manually. Hope the developers can make modifications in the future version.

install.packages("Matrix"),do not install version before 1.5

Hi there!

I am have the same issue. I would like to know if change as(, "dgeMatrix") to as(as(as(., "dMatrix") in the source code worked. I also would like to double check if it is should be changed on the matrix source code. I did not find it on scMetabolism package.

Thanks, Paola

I meet the same problem Error: (converted from warning) 'as(, "dgeMatrix")' is deprecated. Use 'as(as(as(., "dMatrix"), "generalMatrix"), "unpackedMatrix")' instead.
