Help: getting "Error: unexpected symbol in:...." after a lot of commands

[DonCorleone]

I'm trying to load data from the Human Mortality Database. forecast, and plot the Lee-Carter model. This involves the demography package. I keep getting an error of unexpected symbol every time I put another command in which is weird. Is there any fix?

Here is an example of what I'm talking about

Hi, welcome!

To help us help you, could you please prepare a reproducible example (reprex) illustrating your issue? Please have a look at this guide, to see how to create one:

FAQ: How to do a minimal reproducible example ( reprex ) for beginners

A minimal reproducible example consists of the following items: A minimal dataset, necessary to reproduce the issue The minimal runnable code necessary to reproduce the issue, which can be run on the given dataset, and including the necessary information on the used packages. Let's quickly go over each one of these with examples: Minimal Dataset (Sample Data) You need to provide a data frame that is small enough to be (reasonably) pasted on a post, but big enough to reproduce your issue. Let's say, as an example, that you are working with the iris data frame head(iris) #> Sepal.Length Sepal.Width Petal.Length Petal.Width Species #> 1 5.1 3.5 1.4 0.…

It seems like you are concatenating the two functions lca() and forecast() incorrectly, but we can't know for sure based on a screenshot.

+ usa.lca <- lca("bltper_5x1.txt", series="mortality", chooseperiod = FALSE, restype = c("logrates", "rates", "deaths"), interpolate = FALSE )
+ usa.fcast <- (usa.lca, 50)
Error: unexpected symbol in:
"usa.lca <- lca("bltper_5x1.txt", series="mortality", chooseperiod = FALSE, restype = c("logrates", "rates", "deaths"), interpolate = FALSE )
usa.fcast"

Your example is not reproducible so we can just try to guess what the problem is.

This is not valid R code usa.fcast <- (usa.lca, 50) what are you trying to do with this code?

If you run just this part, do you get any error message?

usa.lca <- lca("bltper_5x1.txt", series="mortality", chooseperiod = FALSE, restype = c("logrates", "rates", "deaths"), interpolate = FALSE )
