Hi, Anne, assign Age and Bloodpressure in the correct order to the axes in your call to plot as in: plot(y = Age, x = BloodPressure) abline(SimpleLinearReg1) Hth -- Gerrit --------------------------------------------------------------------- Dr. Gerrit Eichner Mathematical Institute, Room 212 gerrit.eichner at math.uni-giessen.de Justus-Liebig-University Giessen Tel:

Hello, I am trying to graph a regression line using the followings: Age <- c(39, 47, 45, 47, 65, 46, 67, 42, 67, 56, 64, 56, 59, 34, 42, 48, 45, 17, 20, 19, 36, 50, 39, 21, 44, 53, 63, 29, 25, 69) BloodPressure <- c(144, 220, 138, 145, 162, 142, 170, 124, 158, 154, 162, 150, 140, 110, 128, 130, 135, 114, 116, 124, 136, 142, 120, 120, 160, 158, 144, 130, 125, 175) SimpleLinearReg1=lm(Age ~

Hi Anne, I would suggest to change the linear model to lm(BloodPressure~Age), as this model makes more sense in biological means (you would assume that age influences pressure, not vice versa) and also obeys the statistical assumption of weak exogeneity, that age can be measured without error, at least compared to error-prone bp measures.

hi everybody I have to do a lot of Anova with R and I would like to have another type of coefficients coding..

Hi All, I have questions about MANOVA which I am still not sure if appropriately I should use it. For example I have a data set like this: BloodPressure (BP) Weight Height 120 115 165 125 145 198 156 99 176 I know that BloodPressure is correlated with both Weight and Height, however colinearity exists between Weight and Height. When I use BP = Weight + Height

i am working on the project to analyze hedge fund performance, i would appreciate that if you guys could spare some time helping me out with the R code. Thanks. The senario is: i applied BOXPLOT() to plot the performance of all hedge funds with 7 strategies. And right now in this boxplot I need to plot the points of 30 individual hedge funds from my portfolio. And I applied POINTS() and

Hi There, I'm attempting to plot 10 values on a three-dimensional PCA with text labels next to each point. While i have no trouble doing this on 2D plots using the 'text' or 'textxy' function, I cannot find a function to do this on a 3D plot. I am using princomp for my PCA: >PCA<-princomp(eucdata, cor=TRUE) >PCA$scores [,1:3] # the three principal components i

I saw an email about 8.0.1 being not quite out, and planning for 9.0.0. When is 8.0.1 supposed to come out? I installed llvm at develop on x86 on March 30, and its clang says it is version 9.0.0 (trunk 357348). I tried to do another spack install llvm at develop, but it said that I already had it installed. Does that mean there were no changes since March 30, or does spack not look for any

Hi guys, I am doing a project to evaluate the 7 individual fund performance from a portfolio compared with all fund performance utilizing the same strategy. Lets say in total there are 10 strategies and in the portfolio there exist 5 strategies. First, i use the BOXPLOT() and SUBSET() to produce the box plot of all the 5 funds performance individually: #identify funds in strategies within

Hi all, I want maximum control of R, including calculation / buffer output interruption. With Rgui, pressing ESC interrupt both calculation and buffer output. However, with Rterm, ctrl-c works only in calculation, but does not interrupt buffer output: with: i <- 1 while (i > 0) i <- i + 1 which runs an infinite loop, pressing ctrl-c interrupt it. OK. But: rnorm(1000000) is not

Hi R users, I would like to add year information to each point in a scatter plot.

Hi, again, I have to modify my query since my first (too simple) example doesn't reflect my actual problem. Second try: When asking Effect() inside a function to compute an effect of an lmer-fit which uses a data frame local to the body of the function, as in the following example (simplifying my actual application), I get the "Error in is.data.frame(data) : object 'X' not
