Hi everyone, I have a question about calculating r-squared in R. I have tried searching the archives and couldn't find what I was looking for - but apologies if there is somewhere I can find this... I carried out a droughting experiment to test plant competition under limited water. I had: - 7 different levels of watering treatment (1 -7 - from most watered to least watered/) - 15

Hi, When I create an environment object with new.env() and populate it with values then how can I save it into an .RData file properly, so it can be loaded later on in a new session? Saving an environment object with save() or save.image() results in an error message when loading again: Error: protect(): protection stack overflow Regards, benjamin ======================================

Dear list, I read in ?plotmath that I can use bgroup to draw scalable delimiters such as [ ] and ( ). The same technique fails with < > however, and I cannot find a workaround, grid.text(expression(bgroup("<",atop(x,y),">"))) Error in bgroup("<", atop(x, y), ">") : invalid group delimiter Regards, baptiste sessionInfo() R version

hi, I'd like to do graphs like shown on the right panel on the following link: http://www.clinchem.org/cgi/content/full/53/8/1544/F1 (if link doesn't work see attached file) Any help and ideas highly appreciated, thanks in advance. Thomas von K?nel Human Genetics Uni Berne

Dear all I am new R user, and trying to learn more. I am doing linear regression analysis in R with my data. I am trying to find the way to calculate the slope value (coefficient of x) to degree of slope. Please give me idea on this. Thanking you in anticipation Warm regardMS _________________________________________________________________ [[alternative HTML version

Dear all, In a greenhouse experiment we tested performance of 4 different species (B,H,P,R) under 3 different water levels in 10 replications. As response variable e.g. the number of emerging sprouts were measured on three dates. A simple Anova considering every measurement date separately shows a higly significant effect of species and moisture (and partly the interaction of both). The

I have a Sun 7310 storage server. This is running Solaris 10 but it's self-contained and I can't login to it or run Samba on it. I manage it with a web interface. I have a CentOS 5.3 machine that mounts a bunch of file systems via NFS from the Sun server. This works fine. I installed Samba 3.4.5 on the CentOS machine and configured it to share some of the directories that are actually NFS

Dear R user community I wanted to use "bgroup" for plotting a math formula with a big "{" on the left, and nothing on the right. i used text( 10, 10, pos=4, cex=1.8, expression(F(x) == bgroup("{", x, "")), ...) on a 40 x 20 plot. surprisingly, bgroup sets "Phi(xi) = { xi" i.e. replaces alphabetic characters with greek letters in the entire

I am working with a RCB 2x2x3 ANCOVA, and I have noticed a difference in the calculation of sum of squares in a Type III calculation. Anova output is a follows: > Anova(aov(MSOIL~Forest+Burn*Thin*Moisture+ROCK,data=env3l),type=3) Anova Table (Type III tests) Response: MSOIL Sum Sq Df F value Pr(>F) (Intercept) 22.3682 1 53.2141 3.499e-07 *** Forest

Hello, I used the function cor to calculate the pearson correlation coefficient between variables. However, the resulting values do not correspond to the outcome of my excel-calculations, for which I used the formula Cor(x,y)=Cov(x,y)/(SD(x)*SD(y)) So my question is: How does the function "cor" compute the pearson correlation coefficient? Thank you in advance, Ake Nauta

Dear all, I'm using the curve() function to plot discharge Q against water depth a. However, I would like to have a graph of water depth a plotted against discharge Q. How can this be done? Minimal working example: S0 = 0.004 n = 0.04 tanalpha = 1.4/1.5 par(mar = c(5,5,1,1)) # b, l, t, r

I am trying to it a particular nonlinear model common in Soil Science to moisture release data from soil. I have written the function as shown below according to the logist example in Ch8 of Pinheiro & Bates. I am getting the following error (R version 2.1.1) *Error in qr(attr(rhs, "gradient")) : NA/NaN/Inf in foreign function call (arg 1)* Below is the function and data. /#

Dear R-user Suppose I have the following data y=c(2,1,5,8,11,3,1,7,50,21,33,7,60) x=data.frame(y) for(i in 4:nrow(x)) x[i,] =var(x[i-3:i-1,]) I'm trying to get a new variable with the variance of the 3 previous values (just an example) and with NA in the three first positions. I know that my for() is wrong but I'm not able to find my error. Any idea? Thanks, Marlene.

I have a data.frame paint (below-mentioned). In SPlus I used the command raov( MOISTURE ~ BATCH / PROBE ) (you could do raov( MOISTURE ~ BATCH + PROBE%in%BATCH) as well) so that the factors are taken as random. In R this function raov doesn't exist. How can I calculate the same? Maybe with lme, but how? str(paint) ---------- `data.frame': 60 obs. of 5 variables: $ BATCH : Factor

Hello all R listers, I'm struggling to select an appropriate statistical method for my data set. I have collected soil moisture measurements every hour for 2 years. There are 75 sensors taking these automated measurements, spread evenly across 4 treatments and a control. I'm not interested in being able to predict soil future soil moisture trends, but rather in knowing whether the

Dear All, I need to separate one column which is in a format like, "can_region", into two columns like, "can", and "region". Do we have a function in R to do this? Thanks. Regards, Jin [[alternative HTML version deleted]]

ComRades, How do you put a superscript on a scalable delimiter? I want to put 'b' as the power of the expression in the following plot: t <- 1:25 K <- 0.2 y <- ((1-exp(-K*t))/(1-exp(-K*t)*exp(K)))^3 plot(t,y,"l",main="K=0.2, b=3") text(15,5,expression(bgroup("(",frac(1-e^-Kt,1-e^-Kt*e^K),")"))) Plotmath examples in demo(plotmath) do not

Dears, do you know whether it is possible to include any square parantheses (brackets) in an expression to use it as an axis label? e.g. I would like to have a label like (with the sub and superscripts correct): "speed [m s^-1]" I know how to combine an expression with text via paste, but as I run soimething like: a='m*s^{-1}' plot(1:10,main=parse(text=a)) I found now way
