Hello, I do have two different plots from LAD and OLS regression objects like this: # LAD regression and related plot rq(formula = SBP ~ Age) f = coef(rq(SBP ~ Age)) pred = f[1] + f[2]*Age plot (Age, SBP) lines (Age, pred) # OLS regression and related plot Pred = lm(SBP ~ Age) plot (Age, SBP) lines (Age,fitted(Pred)) Well for comparatative reason I would would like to subsume both plots

Dear R community, I am plotting a histogram and would wish to display another variable of the same dataset in a very narrow heatmap just below the x-axis. Never mind the specifics of my task: How can I draw a second graph/image just below a first graph/image? Thank you!

Dear R community, I have a dataframe with say 100 different variables. I wish to regress variable 1 separately on every other variable (2-100) in a linear regression using lm. There must be an easy way to do this without loops, but I have difficulties figuring this out... Can you please help? Thank you and best regards, Georg. ***************************************** Georg Ehret Johns Hopkins

Dear R help, I have the following data frame: structure(list(prochi = c("ind_1", "ind_1", "ind_1", "ind_1", "ind_1", "ind_1", "ind_1", "ind_1", "ind_1", "ind_1"), date_1st_event = structure(c(14784, 14784, 14784, 14784, 14784, 14784, 14784, 14784, 14784, 14784 ), class = "Date"),

Dear R comunity, I am printing a number in a graph using "text(...)" - see code below: "fraction" is my number. I wish to print only two digits of the number and struggle to do this... options(digit=3) does not work... Thank you for your suggestions!

Dear all, I have found some difference of the results between multinom() function in R and multinomial logistic regression in SPSS software. The input data, model and parameters are below: choles <- c(94, 158, 133, 164, 162, 182, 140, 157, 146, 182); sbp <- c(105, 121, 128, 149, 132, 103, 97, 128, 114, 129); case <- c(1, 3, 3, 2, 1, 2, 3, 1, 2, 2); result <- multinom(case ~ choles

Dear R community, I am creating large graphs with hundreds of thousands of datapoints. My usual way for output was pdf, but now I am getting file sizes of >30Mb that do not open well (or at all) in Adobe. Is there a way to reduce the resolution or get rid of overlaying datapoints? Any other idea is also warmly welcome! Thank you and wishing you a good day! Georg. **********************

I am trying to construct a graph of 6 box plots of blood pressures. I want them to be on a single set of axis and I want the SBP to be ontop of the DBP. I have an array bp with the data in it and I tried a[1,]<-c(145,60,147,62,140,57) a[2,]<-c(160,75,160,74,160,70) a[3,]<-c(140,55,140,65,142,55) boxplot(data.frame(a), main = "Blood Pressures", at=c(1,1,2,2,3,3),

Dear R community, I am using 6 variables to test for an effect (by linear regression). These 6 variables are strongly correlated among each other and I would like to find out the number of independent test that I perform in this calcuation. For this I calculated a matrix of correlation coefficients between the variables (see below). But to find the rank of the table in R is not the right

Dear R, I am often adding a total rows or column (sum over all rows or columns) when using table(data$1,data$2)... I do this now by adding the rows/columns and rbind() or cbind()... But there must be a more efficient way.... Could someone please give me a hint? Thank you!

Dear R community, I am using a dataset and would like to define new variables using a R variable: e.g. for (i in 1:10){ dataset$i<-something } But this is not the right way, I get only one variable in "dataset"... How can I change this? Thank you! Georg. ************************ Georg Ehret Johns Hopkins Baltimore, MD [[alternative HTML version deleted]]

Dear R user group, I am working with boxplots and cannot solve the following problem: > data<-c(0,15,0,60,0,0,0,0,0,60,60,0,60,0,30,0) > data [1] 0 15 0 60 0 0 0 0 0 60 60 0 60 0 30 0 > boxplot(data) The boxplot has the first hinge and the mean-bar both at 0... Why is this the mean is clearly >0! Thanking you and wishing you an excellent day, Georg.

Dear Ms and Mr R, I am seeking a visually appealing presentation of 3 variables (~30 datapoints) that are correlated and that should to into the same direction. The objective is to show that they do go in the same direction and what differences there might be while also giving an idea of the values of the variables. I had done this with simple bargraphs for 6 datapoints in the past, but for
