Hello R users,
I'd like to ask a question about how to add a new column. So, below is my
situation.
In order to perform the repeated ANOVA, I first imported the following
table.
score=read.csv("patients_tests.csv");
subject test1 test2 test3 test4 test5 test6
test7
1 ab 0.17687 0.16715 0.17009 0.16480 0.16116 0.24502 0.17975
2 cl 0.18020 0.16618 0.18548 0.14943 0.14289 0.23583 0.17027
3 ds 0.14269 0.12857 0.12972 0.16955 0.14398 0.20865 0.17194
4 ex 0.14626 0.12874 0.15501 0.13019 0.14646 0.21345 0.16023
5 ey 0.16850 0.15654 0.15181 0.18554 0.15642 0.24330 0.16064
6 js 0.13741 0.15516 0.16392 0.15250 0.15416 0.20790 0.15618
7 ms 0.14548 0.16655 0.16561 0.15107 0.14259 0.20386 0.15179
8 pk 0.16246 0.14872 0.15415 0.16553 0.13372 0.25692 0.15096
9 ro 0.18631 0.16128 0.14477 0.16024 0.14063 0.25915 0.19108
10 rt 0.14805 0.15794 0.13665 0.15767 0.13904 0.19171 0.15511
11 sc 0.15510 0.16374 0.16654 0.16864 0.14216 0.20595 0.16847
12 yk 0.18077 0.17320 0.19948 0.15941 0.14053 0.23372 0.18398
Then, I stacked them score2=stack(score);
values ind
1 0.17687 test1
2 0.18020 test1
3 0.14269 test1
4 0.14626 test1
5 0.16850 test1
6 0.13741 test1
7 0.14548 test1
8 0.16246 test1
9 0.18631 test1
10 0.14805 test1
11 0.15510 test1
12 0.18077 test1
13 0.16715 test2
14 0.16618 test2
15 0.12857 test2
.
.
.
This gave me a new structure as shown above, but the subject column was not
included.
So, I'd like to add a new column for subject, but I can't quite figure out
the trick.
Hi Jason,
Perhaps this will do what you want.
library(prettyR)
rep_n_stack(score,to.stack=paste("test",1:7,sep=""))
