Table to R not able to load library

Hi,

macOS Sierra, KNIME 3.5.3, R 3.4.4 from homebrew:

I try to execute a simple command in a Table to R node:

library(MSstats)

Of course packages were installed beforehand and the command works in R. Similarly, other basic R commands work in the node.

I get the following error on the Workbench execunting the node with just the line above:

ERROR  KNIME-Worker-1 Node  Execute failed: R evaluation failed.: "knime.tmp.ret<-NULL;printError<-function(e) print(paste('Error:',conditionMessage(e)));for(exp in tryCatch(parse(text=knime.tmp.script),error=printError)){try(knime.tmp.ret<-eval(exp),silent=True)
if(!is.null(knime.tmp.ret)) {if(knime.tmp.ret$visible) try(print(knime.tmp.ret$value),silent=True)}};rm(knime.tmp.script,exp,printError);knime.tmp.ret$value"

Stacktrace:

In the configuration dialogue i get additionally:

Side notes:

Even executing

knime.tmp.ret<-NULL;printError<-function(e) message(paste('Error:',conditionMessage(e)));tryCatch(knime.tmp.ret<-withVisible(eval(library(MSstats))),error=printError);if(!is.null(knime.tmp.ret)) { if(knime.tmp.ret$visible) {tryCatch(print(knime.tmp.ret$value),error=printError)}};rm(printError);knime.tmp.ret$value

works in R directly.

In the configure dialogue, I get additionally:

library('Cairo');options(device='png',bitmapType='cairo')
png("/private/var/folders/3w/sgbzzwr94nz6n61hdw97b7740000gn/T/knime_iPRG_2015_lfq_a57868/rtmp-dialog-57873/rsnippet-plot.png",width=400.0,height=300.0)"ERROR: R evaluation failed.: "library('Cairo');options(device='png',bitmapType='cairo')

but loading a standard library like dplyr works.

By the way:

Once a failed script was executed in the configure dialogue, it cannot recover and scripts that work before, do not work in that dialogue anymore.

Any ideas? Or any idea how to debug?
