rmsb's Issues

Warning message: `survConcordance.fit` is deprecated

It seems that the code in:

rmsb/R/blrm.r

Lines 680 to 684 in 741eece

function(x, y) {
con <- survival::survConcordance.fit(survival::Surv(y), x)
conc <- con['concordant']; disc <- con['discordant']
- (conc - disc) / (conc + disc)
}

needs to be updated to avoid the repetitive warning:

Warning message:
“'survival::survConcordance.fit' is deprecated.
Use 'concordancefit' instead.
See help("Deprecated")”

Problem with several rmsb errors

I found several possible bugs while using the functions of the new rmsb package. I report the first one, summary(fit) or plot(summary(fit) does not seem to work in this example.
Please check and see what you can do. Thank you.

Unable to install rmsb

I have problems to install the package with this error:

> install.packages("C:/Users/Alberto/Desktop/caterina/rmsb_current.zip", repos = NULL, type = "win.binary")

I can install it when I change the name by removing _current
But then I obtain:

Error in predict.blrm ... may only specify one of kint, ycut leads to Problems with Predict() helper (as it always provides both).

The predict.blrm function will only let you supply one of kint and ycut, which in of itself is not much of a restriction.

However, the Predict() helper function will always supply both - preventing it from working with blrm fits.

Example

getHdata(titanic3)
dd <- datadist(titanic3); options(datadist='dd')
f <- blrm(age~fare, data=titanic3)

#Works
Predict(f, fare=1000)

#Doesn't work
Predict(f, fare=1000, kint=1)

#Works
predict(f, data.frame(fare=1000), kint=1)

#For reference - doesn't work
predict(f, data.frame(fare=1000), kint=1, ycut=1)

Estimation of negative probabilities with predict

I send a reproducible example showing negative probabilities. This occurs when one of the 'y' levels is rare, and the predictor has an extreme value in its range, so I have been slow to notice the problem.

set.seed(836)
data<- data.frame(HE6=sample(1:10, 200, replace = TRUE, prob=c(rep(0.1,6),0.01,0.002,0.19,0.198) ), 
                  Age = sample(1:85, 200, replace = TRUE), EORTC = sample(1:100, 200, replace = TRUE), 
                  linf=rbinom(200, 1,.5),
                  cir=rbinom(200, 1,.5),esquema=rbinom(200, 1,.5), riesgo=factor(rbinom(200, 2,.5)), estadio=factor(rbinom(200, 2,.5)))
head(data)
table(data$HE6)
dd<-datadist(data)
options(datadist='dd')

bsx <- blrm(HE6  ~ cir*rcs(Age,3)+ linf+ pol(EORTC)+esquema+estadio+riesgo, 
            ~ rcs(Age,3)+ pol(EORTC), cppo=function(y) y, data=data) 

newdata <- data.frame(cir=0, Age=85, EORTC= 10, linf=0, riesgo=0, esquema=1, estadio=1)
predict(bsx, newdata, type='fitted.ind') #
