running multiple R scripts in bash script - r

Question

I have 2 R scripts called script1.R and script2.R respectively and I want to run them sequentially as pipeline. To do so, I am trying a bash script to run 2 R scripts, use inputs and arguments (for every script) and returns output (for every script). since there are 2 R scripts, we have 2 steps as follows:
1- this the command for the 1st R script:
Rscript script1.R /path/to/input /path/to/OutputDir argument1 argument2
2- this the command for the 2nd R script:
Rscript script2.R /path/to/output_of_1st_script /path/to/OutputDir argument3 default_yes
to run these 2 R scripts I have made the following bash script but does not return anything! do you know how to fix it?
#!/bin/bash
set -e;
set -u;
OUTDIR1="./output1/";
OUTDIR2="./output2/";
INDIR="./input/";
argument1=$1;
argument2=$2;
argument3=$3;
mkdir ${OUTDIR1} || true;
#to run the 1st script
ls -1 ${INDIR}/*/inputfile.txt | sort -V | while read infile; do
b=$(basename $(dirname "$infile"));
./script1.R \
-v \
run \
-o "${of}" \
-f 0 \
argument1 \
argument2 \
"${b},${infile}" \
;
done
#to run the 2nd script. input of this sript is the output from previous script
ls -1 ${OUTDIR1}/*/output.txt | sort -V | while read outfile1; do
b=$(basename $(dirname "$outfile1"));
./script1.R \
-v \
run \
-o "${of}" \
-f 0 \
argument3 \
"${b},${outfile1}" \
;
done
