question how to add Standard Deviation as "Whiskers" in a simple plot
Dear Researchers, sorry for this simple question. I have a point plot with mean values and i wish to plot line with Standard Deviation as "Whiskers". I calculate the mean+sd and mean-sd, but i can not figure out the way to add the line. mydata <- data.frame(mean=c(0.42,0.41,0.41,0.43,0.45,0.43,0.43,0.42,0.44,0.45,0.45,0.45,0.46,0.43,0.42,0.37,0.44,0.46,0.46,0.39,0.40),

Help boxplot to add mean, standard error and/or stadard deviation
Dear researchers I wish to plot a box plot without the mean line (the black line) and plot only the mean (red square). Futhermore, is it possible to add standard error and/or stadard deviation? This is an example mytest <- c(2.1,2.6,2.7,3.2,4.1,4.3,5.2,5.1,4.8,1.8,1.4,2.5,2.7,3.1,2.6,2.8) boxplot(mytest,lty = "solid") means <- mean(mytest,na.rm=TRUE) points(means, pch = 22, col

Dear Researchers, someone know the right syntax to chose a 5% significance level (threshold) for the inclusion of the model variables in a multiple (linear) regression in backward way? I set the formula in this way, but I don't know to choose the 5% significance? lmodelV <- step(lm(formula=MyFormula[[1]],data=LR.train),direction="backward") thanks in advance gianni

Dear Researchers, I have a large TXT (X,Y,MyValue) file in a directory and I wish to import row by row the txt in a loop to save only the data they are inside a buffer (using inside.owin of spatstat) and delete the rest. The first step before to create a loop row-by-row is to know how many rows there are in the txt file without load in R to save memory problem. some people know the specific

plot.dendrogram xlim/ylim
list(...), I would like to zoom in to the leaves of large trees in a dendrogram plot. The playwith package allows zooming by passing xlim and ylim arguments to the plot call (Hmisc does this too I think). But currently stats:::plot.dendrogram does not accept xlim or ylim. So I would like to enable that. In place of the existing code chunk: xlim <- c(x1 - 1/2, x2 + 1/2) ylim <- c(0,

Hi, I am using the following code as an example function to create multiple y-axes on one plot. I have it working fine however, I can't seem to add a label on the second (right) axis. I have tried adding ylab="y2" in the axis call but, that didn't work; any ideas? Thanks, Jesse Code: function() { par(las=1,xaxs="r",mai=c(1,0.75,1,1)) x<-1:10 y1<-x

explanation why RandomForest don't require a transformations (e.g. logarithmic) of variables
Dear Researches, sorry for the easy and common question. I am trying to justify the idea of RandomForest don't require a transformations (e.g. logarithmic) of variables, comparing this non parametrics method with e.g. the linear regressions. In leteruature to study my phenomena i need to apply a logarithmic trasformation to describe my model, but i found RF don't required this approach.
