...several NAs in the data which is all I can figure that is non-numeric. Any suggestions as to the problem? Is it a problem with having several columns/sets of info for each individual? Thanks for any help anyone can give (I've also used Arlequin and GDA but want non-parametric tests) Michelle DePrenger-Levin My code is: scirconv2 = read.csv("CaScSc070420_2.csv", na.strings="?") CaScSc = scirconv2[1:250,3:21] CaScCo = scirconv2[251:475,3:21] ScCoMWU = wilcox.test(CaScSc, CaScCo, alternative = "two.sided", mu = 0.5, paired = FALSE, exact = NULL, correct = TRUE,...

Hello, I'm in need of running a PVA and want to load {popbio}. However, I can't find it. I can't see where or how to load it. I have added repositories and changed the CRAN mirror site. I see {polynom} and {popgen} but no {popbio} between. What am I doing wrong? Thanks, Michelle [[alternative HTML version deleted]]

Hello, I am trying to use the projection.matrix( ) function and am following the example given. I have my data formatted very similar to the test.census example. > str(AsMi05mat) `data.frame': 1854 obs. of 6 variables: $ Tag : num 501 502 503 504 505 506 507 508 509 510 ... $ Year : int 1995 1995 1995 1995 1995 1995 1995 1995 1995 1995 ... $ Length : num 34

Hello, We are trying to find a function to compute "stress" in our multidimensional scaling analysis of a dissimilarity matrix. We've used "dist()" to create the matrix and "cmdscale()" for the scaling. In order to determine the number of dimensions we would like to plot stress vs. dimensions. However, we cannot find a pre-made command. It seems that other

Hello, I am creating a 3D scatter plot with the cloud function. I ask it to group my rows by a "Treatment" column (there are 4 different groups). I need to know which points in the plot correspond to which rows (which treatment). By default it assigns pchs and cols to each group. When I try to define the colors or point shapes it seems to use the first color and pch for both the first

Hello, I am trying to plot lines in 3 dimensions from a multiple linear model to illustrate the interaction of two of the explanatory variables. I'm trying to use the cloud function (though I'm open to a different function if an easier one exists). I keep getting the error message: Error in cloud(lmPeHa061201, data = PeHa061201, cex = 0.8, main = "Table 99: PeHa", :

Hello, I am running the plot from countCDFxt (popbio). I would like to report the y-axis as a percent instead of the log scale (e^01...). I can add an axis with axis(2, 0:1, line =2) but I'm having trouble understanding how to assign the tic marks (with 'at ='). I'd like to tell it to make tics with the percent value (or decimal if that's my only option) at the equivalent of
