for items in things: while inputfloat != 0: thingsback[][1]=inputfloat//things[] inputfloat=inputfloat-(things[]*thingsback[][1]) things list of n elements, while thingsback list n sub-lists. want both things , thingsback start @ 0th element , loop through recursion. calculation inputfloat//things[] changes 1 index of j-th sublist in thingsback. know [] invalid syntax, used illustrative purposes. it seems there obvious solution, not seeing it. taking guess, think looking index of current item in loop? for index, items in enumerate(things): # stuff using index check out: accessing index in python 'for' loops

currently trying understand dexseq package. have design tsv file , 7 files contains counts. run following command library("dexseq"); design=read.table("dexseq_design.tsv", header=true, row.names=1); ecs = dexseqdatasetfromhtseq(countfiles=c("m0.txt", "m1.txt", "m2.txt", "m3.txt", "m4.txt", "m5.txt", "m6.txt", "m7.txt"), design=design, flattenedfile="genome.chr.gff"); the last command gives , error error in class(sampledata) %in% c("data.frame") : error in evaluating argument 'x' in selecting method function '%in%': error: argument "sampledata" missing, no default what error means , how fix it? while loading package dexseq there warning warning message: replacing previous import ‘ggplot2::position’ when loading ‘deseq2’

i have column of dates , numbers this: 24/01/2016 1 0.123 24/01/2016 2 0.121 24/01/2016 3 0.104 24/01/2016 4 0.116 24/01/2016 5 0.091 ... how can transform column in excel appears in three columns such: 24/01/2016 1 0.123 24/01/2016 2 0.121 24/01/2016 3 0.104 24/01/2016 4 0.116 24/01/2016 5 0.091 ... you can find answer here . in short, 1 of answers use following formula: =indirect(address((row($a1)-1)*3+column(a1),1))

when c program calls system() run unix command, know it's possible pass arguments command, , according stackoverflow answer (from high-rep user), the system() call uses shell execute command . it surprised me see system("ls -lh >/dev/null 2>&1"); example system() call c program, since looks using same whitespace delimited "words" shell uses interactively. from standpoint sysadmin, i'd understand provisos , pitfalls when system() call going executed within c program on files or commands on system. passing whitespace-containing filenames shell script very issue-prone ; there similar issues when c program calling command? or make point blunter (though less exact): c program written novice break on whitespace-containing filenames shell script? there nothing in c source here, string pass system() run in shell context. shell parse string, c program doesn't. if @ system() function prototype : #include <stdlib.h> ...
