I like to add a solution to my existing watersports booking site. Problem: Currently, my website allows user to search, book and pay for their watersports activity with selected vendors. However, there are times when vendors do not update in the system back-end on their availability. Hence, when users search, book and pay, there may be situations when the actual slot is actually taken up, and/or for whatever reason, the vendor is unable to fulfill the booking. Solution: Hence, i need to have a "confirmation" stage where after user search, books and pays, the "confirmation" email is sent to the vendor for him to accept/reject the booking. The results is forwarded via email to the user. So far, the transaction will be processed, and refunded offline. However, i am exploring if the payment gateway allows me to "hold" the payment. Nevertheless, the important thing is to prevent a non-fulfillment of booking.

I have csv file with a binary outcome variable (0/1) and 5 predictor variables (1 continuous, 4 categorical) from which I have derived a logistic regression. I now want to turn this logistic regression model into a nomogram. I have attempted to use the nomogram function from the "rms" package but having trouble getting it to run. I suspect the problem may be in part due to having no idea how to set the data up. This is the code I have used: library(rms) setwd("/Users/General/Dropbox/NOMOGRAM/test_data") mydata <- read.table("stata_test.csv", header=TRUE, sep=",") attach(mydata2) f <- glm(Non_Responder ~ BMI__40 + K_L__4 + WOMAC_Total_score_preop, family=binomial(logit), data=mydata) nom <- nomogram(f, fun=function(x)1/(1+exp(-x))) Everything works fine until I get to the nomogram function where I keep getting the following error: "Error in lims[[i]] : subscript out of bounds" Something to do with the dataset set-up? With ho...
