Help with 'estimateCellComposition'

[pmishra]

Hi,

I am trying to estimate cell composition using reference data obtained using the 'getRefSet' function. I run the following line,

tmp <- estimateCellComposition(g=ref, q=dat) # dat is methylation profile of 275955 CpGs in a sample (=nrow(ref)).

However, I am getting 'could not find function "estimateCellComposition' error message. I am not able to understand the error because sesame package is loaded as you can see below in the output from sessionInfo(),

attached base packages:
[1] parallel stats graphics grDevices utils datasets methods
[8] base

other attached packages:
[1] sesame_1.20.0 sesameData_1.20.0 ExperimentHub_2.8.1
[4] AnnotationHub_3.10.0 BiocFileCache_2.10.1 dbplyr_2.4.0
[7] BiocGenerics_0.46.0

Would appreciate for any help!
