graph2ppt connection error when exporting Seurat FeaturePlot in R 4.2 Rmarkdown

[JesseRop]

Dear developer,

Many thanks for the great tool! Very handy.
I'll be grateful for your assistance with the issue below.

I updated my rstudio to the latest version and R to 4.2 and now not able to export getting the error
'Warning in .Internal(environment(fun)) :
closing unused connection 3 (/var/folders/9h/zbzv_b3j3wz2r6mdgw9s2p04000lw8/T//RtmpkTyPis/filee19561b44ad/raster-rId000002.png)

I have tried making a reproducible example with the dataset loaded into pbmc found here ( https://cf.10xgenomics.com/samples/cell/pbmc3k/pbmc3k_filtered_gene_bc_matrices.tar.gz )

The code can be run in rmarkdown as below

title: "export trial"
output: html_document
date: "2023-01-25"

knitr::opts_chunk$set(echo = TRUE)

library(dplyr)
library(Seurat)
library(export)

# Load the PBMC dataset
pbmc.data <- Read10X(data.dir = "/Users/jr35/Google Drive/My Drive/PHD_documents/trial_datasets/filtered_gene_bc_matrices/hg19/")
# Initialize the Seurat object with the raw (non-normalized data).
pbmc <- CreateSeuratObject(counts = pbmc.data, project = "pbmc3k", min.cells = 3, min.features = 200)

pbmc <- FindVariableFeatures(pbmc, selection.method = "vst", nfeatures = 2000)

pbmc <- ScaleData(pbmc)
pbmc <- RunPCA(pbmc, features = VariableFeatures(object = pbmc))

pbmc <- FindNeighbors(pbmc, dims = 1:10)
pbmc <- FindClusters(pbmc, resolution = 0.5)

pbmc <- RunUMAP(pbmc, dims = 1:10)

Plotting and exporting

FeaturePlot(pbmc, features = "CCR7", dims = c(1,2), pt.size = 1.5, label = T, label.size = 5, repel = T) 
graph2ppt(file = '/Users/jr35/Google Drive/My Drive/PHD_documents/test_exp.ppt')

The output of session info is below

Hmm thanks for the bug report.
I can confirm that

library(Seurat)
data("pbmc_small")
pl = FeaturePlot(object = pbmc_small, features = 'PC_1')
graph2ppt(x=pl, file="./test.pptx", width=7, height=5)

also produces the error

Error in open.connection(con, "rb") : cannot open the connection
In addition: Warning message:
In open.connection(con, "rb") :
  cannot open file 'C:\Users\bherr\AppData\Local\Temp\RtmpCQqwZP\file1f6849f02517/raster-rId000002.png': No such file or directory

for me - haven't figured out yet where that is coming from...

graph2doc(x=pl, file="./test.docx", width=7, height=5)
does seem to work though, if that's of any help...

Will try to look a bit further where this is coming from...

I have the similar problem, and I have just updated all my R CRAN packages 3 hours ago. But I found that the ggplot object (like plots made through ggsurvplot() and ggplot2() function ) works fine, but the plotsI build through dotplot() function using the enrichr package for enrichment analysis got the error. I hope my experience will help to find the bug.

Help!!! I also suffered the same problem.

Error in open.connection(con, "rb") : cannot open the connection
In addition: Warning message:

Hope some can find the solutions, really thanks.
