Fitting data to logistic function in R
I'm trying to fit world sales data for BEV and PHEV to a logistic growth function.
For an example, I'm using R-code for Logistic Growth Model of Australian Population in R (by Elise Gould)
But with this method I'm getting the error:
Error in qr.default(.swts * gr) :
NA/NaN/Inf in foreign function call (arg 1)
In addition: Warning message:
In Ops.factor(xmid, input) : ‘-’ not meaningful for factors
My data is:
EV_temp<-structure(list(Country = structure(c(21L, 21L, 21L, 21L, 21L,
21L, 21L, 21L, 21L, 21L, 21L, 21L, 21L), .Label = c("Australia",
"Brazil", "Canada", "Chile", "China", "Finland", "France", "Germany",
"India", "Japan", "Korea", "Mexico", "Netherlands", "New Zealand",
"Norway", "Others", "Portugal", "South Africa", "Sweden", "Thailand",
"Total", "United Kingdom", "United States"), class = "factor"),
Year = structure(1:13, .Label = c("2005", "2006", "2007",
"2008", "2009", "2010", "2011", "2012", "2013", "2014", "2015",
"2016", "2017"), class = "factor"), TotalSales = c(1.89,
2.23, 2.69, 5.15, 7.48, 14.26, 61.33, 179.03, 381.3, 703.65,
1239.45, 1982.04, 3109.05)), class = "data.frame", row.names = c(NA,
-13L), .Names = c("Country", "Year", "TotalSales"))
Code:
EV.ss <- nls(TotalSales ~ SSlogis(Year, phi1, phi2, phi3), data = EV_temp)
If anyone could point me in the correct direction in solving this it would be greatly appreciated.

Just a guess, but looks like this is becauseYear
is a factor.

Thanks yes didn't think of checking that. :) code to fix it: EV_temp$Year<-as.numeric(as.character(EV_temp$Year))
