"v38"  "v39"  "v40"  "v41"  "v42"  "v43"  "v44"  "v45"  "v46" 

 [77] "v47"  "v48"  "v49"  "v50"  "v51"  "v82"  "v83"  "v84"  "v85"  "v86"
"v87"  "v88"  "v89"  "v90"  "v91"  "v92"  "v93"  "v94"  "v95" 

 [96] "v96"  "v97"  "v98"  "v99"  "v100" "v101" "v102" "v103" "v104" "v105"
"v106" "v107" "v108" "v109" "v110" "v111" "v112" "v113" "v114"

(...)

 [856] "v856" "v857" "v858" "v859" "v860" "v861" "v862" "v863" "v864" "v865"
"v866" "v867" "v868" "v869" "v870" "v871" "v872" "v873" "v874"

[875] "v875" "v876" "v877" "v878" "v879" "v880" "v881" "v882" "v883" "v884"
"v885" "v886" "v887" "v888" "v889" "v890" "v891" "v892" "v893"

[894] "v894" "v895" "v896" "v897" "v898" "v899" "v900" "v901" "v902" "v903"

"v923" "v924" "v925" "v926" "v927" "v928" "v929" "v930" "v931"

 

And I want obtain another dataset with sort columns names, and I do this:

 

data1<-data[,sort(colnames(data))]

 

names(data1)

 

[1] "v1"   "v10"  "v100" "v101" "v102" "v103" "v104" "v105" "v106" "v107"

[115] "v201" "v202" "v203" "v204" "v205" "v206" "v207" "v208" "v209" "v21"
"v210" "v211" "v212" "v213" "v214" "v215" "v216" "v217" "v218"

[134] "v219" "v22"  "v220" "v221" "v222" "v223" "v224" "v225" "v226" "v227"
"v228" "v229" "v23"  "v230" "v231" "v232" "v233" "v234" "v235"

(...)

[856] "v87"  "v870" "v871" "v872" "v873" "v874" "v875" "v876" "v877" "v878"
"v879" "v88"  "v880" "v881" "v882" "v883" "v884" "v885" "v886"

[875] "v887" "v888" "v889" "v89"  "v890" "v891" "v892" "v893" "v894" "v895"
"v896" "v897" "v898" "v899" "v9"   "v90"  "v900" "v901" "v902"

[894] "v903" "v904" "v905" "v906" "v907" "v908" "v909" "v91"  "v910" "v911"
"v912" "v913" "v914" "v915" "v916" "v917" "v918" "v919" "v92" 

[913] "v920" "v921" "v922" "v923" "v924" "v925" "v926" "v927" "v928" "v929"
"v93"  "v930" "v931" "v94"  "v95"  "v96"  "v97"  "v98"  "v99"

 

 

But I would like obtain, something like this: "v1"  "v2"  "v3" "v4" "v5"
"v6"  (...)   "v928"  "v929"  "v930" "v931" 

 

It's possible?

 

Thanks in advance
