Re: [R] How to load data file without attribute names?
Thank you very much. What I actually do was data1 - read.delim(path,head=FALSE,sep=,) motor_UPDRS -data1[5] qqnorm(motor_UPDRS) I eventually noticed that I missed a , in the second command. And I cannot retrieve a vector correctly. -- View this message in context: http://r.789695.n4.nabble.com/How-to-load-data-file-without-attribute-names-tp3061489p3062333.html Sent from the R help mailing list archive at Nabble.com. __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
[R] How to load data file without attribute names?
Hi all, I'm new to R and I'm struggling with loading a data file without attribute names, like: 1,72,0,5.6431,28.199 1,72,0,12.666,28.447 1,72,0,19.681,28.695 1,72,0,25.647,28.905 It has no names for the columns nor the rows. I tried data - read.table(path,header = FALSE, sep = ,) and it seems to work. But later, when I try qqnorm to plot the graph, it gives me the error msg: xy.coords(x, y, xlabel, ylabel, log) : 'x' and 'y' lengths differ I think the reason might be that I load the file wrongly. What should I do in this case? -- View this message in context: http://r.789695.n4.nabble.com/How-to-load-data-file-without-attribute-names-tp3061489p3061489.html Sent from the R help mailing list archive at Nabble.com. __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
Re: [R] How to load data file without attribute names?
You need to follow the posting guide and show exactly what you did. I
read in your data and can print it. You did not show what 'x', and
'y' were in your data:
myData - read.table('clipboard', sep=',')
myData
V1 V2 V3 V4 V5
1 1 72 0 5.6431 28.199
2 1 72 0 12.6660 28.447
3 1 72 0 19.6810 28.695
4 1 72 0 25.6470 28.905
plot(myData$V4, myData$V5)
You need to at least do
str(x)
str(y)
to show what you are working with.

and it seems to work. But later, when I try qqnorm to plot the graph, it
gives me the error msg:
xy.coords(x, y, xlabel, ylabel, log) :
'x' and 'y' lengths differ
I think the reason might be that I load the file wrongly. What should I do
in this case?

What should I do in this case? Hi 44whyfrog, I guess (and it's a wild one) that you have simply typed in the usage arguments, and these have little or no relation to what is in data. If I were in your pond, I would first try: names(data) to see what the names of your columns are. If you do find columns named x and y, try: length(data$x) length(data$y) The error message may relate to the fact that you already have an x or a y object hanging around in your workspace, and they have different lengths.
