Hi R users,

I have a folder (called genotype) with 652 files; the file names are  GTEX-1A3MV.out, GTEX-1A3MX.out, GTEX-1B8SF.out, etc; in each file,  only one column of data without a header as below

A total of 20528 rows;

I need to read all those 652 files in the genotype folder and then reshape the one column in each file as:
SampleID             201        238        245        ....   983255         983766
GTEX-1A3MV     2/2         3/4        1/2                         3/3         None

There are 10264 data columns plus the sample ID column, so 10265 columns in total after data reshaping.

After reading those 652 file and reshape the one column in each file, I will stack them by the rbind function, then I have a file with a dimension of 653 row, 10265 column.

Thank you,
