I have installed the pROC package a month ago with the following code without problems:
<br>#load and call the necessary package.
<br>install.packages ("pROC")
<br>library ("pROC")
<br>
<br>#import the excel.
<br>library (readxl)
<br>dfcor <- read_excel ("C: /Users/pe3re/Downloads/Curvas-COR-master/Curvas-COR-master/FCM.xlsx", col_types = c ("numeric", "numeric"))
<br>
<br>
<br>
<br>roc <-roc (dfcor $ true, dfcor $ pred)
<br>
<br>plot (roc)
<br>
<br>auc (roc)
<br>
<br>
<br>#we draw the curve beautiful.
<br>#insert AUC and IC
<br>rocobj <- plot.roc (dfcor $ true, dfcor $ pred, main = "Confidence intervals", percent = TRUE, ci = TRUE, print.auc = TRUE)
<br>
<br>#we create object to plot the default CI at 95% CI. Boots Default: 2000.
<br>ciobj <- ci.se (rocobj, specificities = seq (0, 100, 5))
<br>#insert the IC
<br>plot (ciobj, type = "shape", col = "# 1c61b6AA") # plot as a blue shape
<br>
<br>Today I have updated to the new version and it has given me problems. I have followed the code on the page and I get the same error again when using the confidence intervals:
<br>
<br>roc1 <- roc (true ~ pred, dfcor, percent = TRUE,
<br> ci = TRUE, boot.n = 100, ci.alpha = 0.9, stratified = FALSE,
<br> plot = TRUE, auc.polygon = TRUE, max.auc.polygon = TRUE, grid = TRUE,
<br> print.auc = TRUE, show.thres = TRUE)
<br>
