Re: [R] Mann-Whitney U
Hi, I do want to use the Mann-Whitney test which ranks my data and then uses those ranks rather than the actual data. Here is the R code i am using: group1- c(1.34,1.47,1.48,1.49,1.62,1.67,1.7,1.7,1.7,1.73,1.81,1.84,1.9,1.96,2,2,2.19,2.29,2.29,2.41,2.41,2.46,2.5,2.6,2.8,2.8,3.07,3.3) group2- c(0.98,1.18,1.25,1.33,1.38,1.4,1.49,1.57,1.72,1.75,1.8,1.82,1.86,1.9,1.97,2.04,2.14,2.18,2.49,2.5,2.55,2.57,2.64,2.73,2.77,2.9,2.94,NA) result - wilcox.test(group1, group2, paired=FALSE, conf.level = 0.95, na.action) paired = FALSE so that the Wilcoxon rank sum test which is equivalent to the Mann-Whitney test is used (my samples are NOT paired). conf.level = 0.95 to specify the confidence level na.action is used because i have a NA value (i suspect i am not using na.action in the correct manner) When i use this code i get the following error message: Error in arg == choices : comparison (1) is possible only for atomic and list types When i use this code: group1- c(1.34,1.47,1.48,1.49,1.62,1.67,1.7,1.7,1.7,1.73,1.81,1.84,1.9,1.96,2,2,2.19,2.29,2.29,2.41,2.41,2.46,2.5,2.6,2.8,2.8,3.07,3.3) group2- c(0.98,1.18,1.25,1.33,1.38,1.4,1.49,1.57,1.72,1.75,1.8,1.82,1.86,1.9,1.97,2.04,2.14,2.18,2.49,2.5,2.55,2.57,2.64,2.73,2.77,2.9,2.94,NA) result - wilcox.test(group1, group2, paired=FALSE, conf.level = 0.95) I get the following result: Wilcoxon rank sum test with continuity correction data: group1 and group2 W = 405.5, p-value = 0.6494 alternative hypothesis: true location shift is not equal to 0 Warning message: cannot compute exact p-value with ties in: wilcox.test.default(group1, group2, paired = FALSE, conf.level = 0.95) The W value here is 405.5 with a p-value of 0.6494 in SPSS, i am ranking my data and then performing a Mann-Whitney U by selecting analyze - non-parametric tests - 2 independent samples and then checking off the Mann-Whitney U test. For the Mann-Whitney test in SPSS i am gettting the following results: Mann-Whitney U = 350.5 2- tailed p value = 0.643 I think maybe the descrepancy has to do with the specification of the NA values in R, but i'm not sure. If anyone has any suggestions, please let me know! I hope i have provided enough information to convey my problem. Thank-you, Nat __ Natalie, It's best to provide at least a sample of your data. Your field names suggest that your data might be collected in units of mm^2 or some similar measurement of area. Why do you want to use Mann-Whitney, which will rank your data and then use those ranks rather than your actual data? Unless your sample is quite small, why not use a two sample t-test? Also,are your samples paired? If they aren't, did you use the paired = FALSE option?

[R] Mann-Whitney U
Hi, Could someone please tell me how to perform a Mann-Whitney U test on a dataset with 2 groups where one group has more data values than another? I have split up my 2 groups into 2 columns in my .txt file i'm using with R. Here is the code i have so far... group1 - c(LeafArea2) group2 - c(LeafArea1) wilcox.test(group1, group2) This code works for datasets with the same number of data values in each column, but not when there is a different number of data values in one column than another column of data. Is the solution that i have to have a null value in the data column with the fewer data values? I'm testing for significant diferences between the 2 groups, and the result i'm getting in R with the uneven values is different from what i'm getting in SPSS. Help please!

Re: [R] select if + other questions
Hi, Does anyone know how to skip variables (or columns) in R. Say, for example i had PUMFID position1 and Y_Q10A position 33 and i do not want to include all the variables in between. Is there a way to do this in R when you are extracting variables from a large .txt file with many, many variables?

I don't deal with weigthed data so I'm not a good source Have a look at help for something like lm in the stats package (part of the base installation) for an example. ?lm weight is the fourth argument down.

Re: [R] select if + other questions
Hi John, I figured out the skipping of variables using a first subset then making a second subset it worked! Thanks, Natalie __ You need to have a look at Chapter 5 of the Intro to R. I would recommend downloading the pdf and printing it out. It is not an easy read but it should help. newdata - mydata[, c(PUMDID, Y_Q10A)] or newdata - mydata[, c(1,33)] should do the trick --- Natalie O'Toole [EMAIL PROTECTED] wrote: Hi, Does anyone know how to skip variables (or columns) in R. Say, for example i had PUMFID position1 and Y_Q10A position 33 and i do not want to include all the variables in between. Is there a way to do this in R when you are extracting variables from a large .txt file with many, many variables? Thanks, Nat __ Yes but I believe it will vary depending on what package you're using. I don't deal with weigthed data so I'm not a good source Have a look at help for something like lm in the stats package (part of the base installation) for an example. ?lm weight is the fourth argument down. However for more information try http://finzi.psych.upenn.edu/search.html and type in weight.

Hi all, I have 2 questions: 1)How do I calculate the mean on an imported txt file? I've imported the file below and that's what it looks like imported. How do I then calcuate the mean, median, or mode on the column LeafArea using the desktop R package? Any help would be greatly appreciated!!

[R] aggregate similar to SPSS
Hi, Does anyone know if: with R can you take a set of numbers and aggregate them like you can in SPSS? For example, could you calculate the percentage of people who smoke based on a dataset like the following: smoke = 1 non-smoke = 2 variable 1 1 1 2 2 1 1 1 2 2 2 2 2 2 When aggregated, SPSS can tell you what percentage of persons are smokers based on the frequency of 1's and 2's. Can R statistical package do a similar thing? Thanks, Nat __ R-help@stat.math.ethz.ch 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.
