This is probably a very simple question but I am completely stumped!I am trying to do shapiro.wilk(x) test on a relatively small dataset(75) and each time my variable and keeps coming out as 'NULL', and> shapiro.test(fcv)Error in complete.cases(x) : no input has determined the number of cases my text file looks like this: case 1.600972896 1.534026106 1.633468456 1.69019608 1.686636269 1.713490543 1.460897843 1.604226053 1.547774705 1.575187845 1.50242712 1.489958479 1.555094449 1.56937391 1.46686762 1.583198774 1.59439255 1.627365857 1.596597096 1.598790507 1.596597096 1.613841822 1.607455023 1.586587305 1.72427587 1.668385917 1.743509765 1.5774918 1.709269961 1.507855872 1.650307523 1.670245853 1.721810615 1.613841822 1.586587305 1.658011397 1.595496222 1.662757832 1.521138084 1.564666064 1.515873844 1.596597096 1.617000341 1.621176282 1.598790507 1.73479983 1.498310554 1.571708832 1.426511261 1.698970004 1.534026106 1.5774918 1.682145076 1.689308859 1.654176542 1.526339277 1.545307116 1.658964843 1.638489257 1.557507202 1.604226053 1.627365857 1.651278014 1.627365857 1.559906625 1.720159303 1.64738297 1.62324929 1.698970004 1.704150517 1.57863921 1.558708571 1.681241237 1.539076099 1.5132176 Any ideas? -- View this message in context: http://r.789695.n4.nabble.com/Null-tp3498261p3498261.html Sent from the R help mailing list archive at Nabble.com.
There were no problems when I repeated the test with data provided. I simply created a vector xxxx<-c(1.600972896,1.534026106,1.633468456,1.69019608,1.686636269,1.713490543,1.460897843,1.604226053,1.547774705,1.575187845,1.50242712,1.489958479,1.555094449,1.56937391,1.46686762,1.583198774,1.59439255,1.627365857,1.596597096,1.598790507,1.596597096,1.613841822,1.607455023,1.586587305,1.72427587,1.668385917,1.743509765,1.5774918,1.709269961,1.507855872,1.650307523,1.670245853,1.721810615,1.613841822,1.586587305,1.658011397,1.595496222,1.662757832,1.521138084,1.564666064,1.515873844,1.596597096,1.617000341,1.621176282,1.598790507,1.73479983,1.498310554,1.571708832,1.426511261,1.698970004,1.534026106,1.5774918,1.682145076,1.689308859,1.654176542,1.526339277,1.545307116,1.658964843,1.638489257,1.557507202,1.604226053,1.627365857,1.651278014,1.627365857,1.559906625,1.720159303,1.64738297,1.62324929,1.698970004,1.704150517,1.57863921,1.558708571,1.681241237,1.539076099,1.5132176) and performed shapiro.test(xxxx) with following results: W = 0.9876, p-value = 0.677 As far as I understand R, complete.cases has nothing to do with normality check of single vector. pcc wrote:> > This is probably a very simple question but I am completely stumped!I am > trying to do shapiro.wilk(x) test on a relatively small dataset(75) and > each time my variable and keeps coming out as 'NULL'-- View this message in context: http://r.789695.n4.nabble.com/Null-tp3498261p3498607.html Sent from the R help mailing list archive at Nabble.com.
Maybe you were doing something like
fcv <- read.csv('fcv.csv')
instead of
fcv <- read.csv('fcv.csv')[1]
(I haven't tested this.)
