'from' must be a finite number

[eve1]

hi i need help, i need to normalize some data using log, but the error "Error in seq.default(min(log(Datos$TotalWorkingYears)), max(log(Datos$TotalWorkingYears)), :
'from' must be a finite number" i don't know what to do

exp <- hist(Datos$TotalWorkingYears, prob =TRUE, main= 'Experiencia de los empleados', ylab='frecuencia', col='lightsalmon1') 
x<- seq(min(log(Datos$TotalWorkingYears)) , max(log(Datos$TotalWorkingYears)), length=50)
f<-dnorm(x, mean= mean(log(Datos$TotalWorkingYears),sd=sd(log(Datos$TotalWorkingYears)))
lines(x,f,col ='darkviolet', lwd=2)

If some of your data equals zero or is negative, log() returns NA. That may be the source of your problem.

If that's the issue, you might try:

x<- seq(min(log(Datos$TotalWorkingYears), na.rm=TRUE) , max(log(Datos$TotalWorkingYears), na.rm=TRUE), length=50)

[eve1]

I filtered the data none of them are zero or negative

[eve1]

i just tried it, but the error still goes on

[bloosmore]

What does

min(log(Datos$TotalWorkingYears), na.rm=TRUE)

return?

[eve1]

the same error: "Error in seq.default(min(log(Datos$TotalWorkingYears), na.rm = TRUE), :
'from' must be a finite number"

[bloosmore]

Hmmm... Can you put the following code into it's own R chunk or run it from the console by itself? What is the output?

min(log(Datos$TotalWorkingYears), na.rm=TRUE)

(This alone shouldn't give the from error because you aren't asking to create a sequence here.)

Also, could you post the Datos$TotalWorkingYears vector (depending how long it is)?

To be clear, I suspect the problem is with the data itself, not your code, as the following seems to work fine:

x<- seq(min(log(airquality$Ozone), na.rm=TRUE) , max(log(airquality$Ozone), na.rm=TRUE), length=50)

[eve1]

ok, if i put the code in the chunk it doesn't throw me any error by itself,

the vector is

i used the filter

filter(Datos, Datos$TotalWorkingYears>0) but it didn't work for the error

[bloosmore]

That helps! So there is at least one '0' datapoint and log(0) = -Inf which is causing a problem in the seq() function that isn't picked up by na.rm. How about:

TWY <- Datos$TotalWorkingYears[Datos$TotalWorkingYears>0]
min.x <- min(log(TWY))
max.x <- max(log(TWY))

x<- seq(min.x, max.x, length=50)
