Special characters problem while using R-Nodes - UTF-8

KNIME Extensions Scripting
#1

Hello,

we use KNIME Table - R node and R - KNIME Table.

Our data is UTF-8 and contains some special characters (German Umlaute). These create problems after they are processed in local R when returned back to KNIME with R-Table.

Is there a way to solve this?

Thanks

Have you tried escaping them with back ticks?

Hello,

I could not figure out this one. The problem is as far as I understand already in the import to R.

I have the setting to use KNIME with UTF-8 as it is needed for other import/export steps.

It seems that the data is loaded to R from the tempfile as

R <- read.csv("C:/temp/R-inDataTempFile-1225241597915727259.csv", header = TRUE, row.names = 1);

I would need to read asl

R <- read.csv("C:/temp/R-inDataTempFile-1225241597915727259.csv", header = TRUE, row.names = 1, encoding="UTF-8");

but I can not set the parameter UTF-8.

Thanks
