Hello, This is the first time i'm trying to plot in R. I want to plot estimates of OR and their confidence limits, like a scatter plot: the vertical axis should be the estimated OR (with upper and lower conf. limits), and the horizontal exis should be fixed values: (1,0.8,0.7,0.6,0.5,0.4)
Here is a part of my code: ...ests=matrix(ncol=3,nrow=6) ests[,1]<-c(mean(or1),mean(or14),mean(or15),mean(or16),mean(or17),mean(or18)) ests[,2]<-c(cl1,cl14,cl15,cl16,cl17,cl18) ests[,3]<-c(cu1,cu14,cu15,cu16,cu17,cu18) x1<-c(1,0.8,0.7,0.6,0.5,0.4)... Now I have a matrix with three columns: estimate, lower limit of the confidende interval, and upper limit of the confidence interval: [,1] [,2] [,3] [1,] 1.011794 0.6400744 1.383514 [2,] 1.646535 1.0421947 2.250875 [3,] 2.118518 1.3364878 2.900549 [4,] 2.709806 1.6899134 3.729698 [5,] 3.570759 2.2510895 4.890428 [6,] 4.874569 2.9081958 6.840942 The first value in x1 fit the first row in the matrix, etc.. I tried the function plotEst like this: plotEst(ests,y = dim(ests)[1]:1, xlab="sensitivity", xtic=x1, xlim=range(xtic)) and got the Error: Error in strsplit(x, as.character(split), as.logical(extended), as.logical(fixed), : non-character argument in strsplit() What am I missing? Thank you, Sigalit.
