r - Plot with specific variables -

-



i have table matrix tab seprated:

name    variable    value abc12   present in    4 abc12   present in b    2 abc12   total present in ab 6 abc12   present in c    5 abc12   present in d    5 abc12   total present in cd 10 abcd12  present in    2 abcd12  present in b    6 abcd12  total present in ab 8 abcd12  present in c    4 abcd12  present in d    8 abcd12  total present in cd 12

i want plot in geom_bar, x-axis name , y- axis value.

x-axis name has show

1 bar - total present in ab - fill present in , present in b

2 bar - total present in cd - fill present in c , present in d

python - Read npy file directly from S3 StreamingBody -

i have many .npy (numpy) , .json files saved in s3, need download , load these files. for json files downloading files , loading dictionary using following code: obj = s3.object(bucket, key) response = obj.get() body = response['body'].read().decode('utf-8') data = json.loads(body) that way avoid writing .json file disk , reading it. now want same .npy files, equivalent? currently downloading file, saving temp file on disk , loading np.load avoid if possible. following https://stackoverflow.com/a/28196540/3509999 : obj = s3.object(bucket, key) io.bytesio(obj.get()["body"].read()) f: # rewind file f.seek(0) arr = np.load(f) wiki

i start using kotlin , defined interface this: interface aadapter<vh : recyclerview.viewholder> { fun oncreateaviewholder(parent: viewgroup): vh fun onbindaviewholder(v: vh, position: int) } and when try use on code: class klasa ( private val adapter: aadapter<*> ) { fun dosth(){ //... val vh = this.adapter.oncreateaviewholder(parent) //on below line error adapter.onbindaviewholder(v, position) //... } } i error out-projected type 'aadapter<*>' prohibits use of 'public abstract fun onbindaviewholder(v: t, position: int): unit i tied add "in" or "out" definition i'm confused. how allow it. replace aadapter<*> aadapter<recyclerview.viewholder> . class klasa ( private val adapter: aadapter<recyclerview.viewholder> ) { // ... because have declared aadapter has type parameter vh type subclass of recyclerview.
