I am plottitng the reliability v/s time plot in R using WeibullR package. But by default it is printing Unreliability vs time. Is there any way to make it reliability vs time graph?? Thanks in advance

library used:

library(WeibullR)

library(WeibullR) df <- data.frame(time = c(10000, 10000, 20000, 20000, 30000, 30000, 30000, 30000, 40000, 50000, 50000, 60000, 70000, 70000, 70000, 70000, 80000, 80000, 80000, 80000, 90000, 90000, 100000), event = rep(1, 23)) weibl <- 1- wblr(df, col="darkgreen",label="censored dataset", dist = "weibull2p", ylab = "check") weibl_fit <- wblr.fit(weR, col = "Red", method.fit = "rr") data <- wblr.conf(weibl_fit, col="blue") plot(data)

Default it is plotting unreliability[%] vs Time to failure. Expected is Reliability vs time.

Here df is the dataframe having time and event as the two column names. For below library it is required that your column names should in this format(viz: event and time).

To plot reliability vs time I'm using above df as input.

library(WeibullR)

weibl <- wblr(df, col="darkgreen",label="censored dataset", dist = "weibull2p", ylab = "Unreliability")

data <- wblr.fit(weibl, col = "Red", method.fit = "mle", dist = "weibull2p") reliability<- data$data$dpoints

plot(x =reliability$time, y = ((1-reliability$ppp)*100), xlab = "Time", ylab = "reliability", xlim=c(1000,100000), ylim=c(0,100), col="orange")

Above plot will give you reliability vs time plot.
