cellchat.NL <- readRDS("data/cellchat_humanSkin_NL.rds")
cellchat.LS <- readRDS("data/cellchat_humanSkin_LS.rds")

（1）报错界面

no slot of name "images" for this object of class

（2）原因

这是因为cellchat版本不同导致的，可以先使用updateCellChat函数将之前对象更新后再执行mergeCellChat合并的操作

（3）解决方法

cellchat.NL <- updateCellChat(cellchat.NL)
cellchat.LS <- updateCellChat(cellchat.LS)
object.list <- list(NL = cellchat.NL, LS = cellchat.LS)
cellchat <- mergeCellChat(object.list, add.names = names(object.list))
cellchat
