Using a list of models to make predictions over a list of results using lapply in R

Time：02-18

I have a large list of models that I built using lapply with the following code (these lists are too long to show the whole data but I used the corresponding code to set the models up):

table_list <- raw2 %>%
  group_by(Lake_name) %>%
  group_split()

model_list <- lapply(table_list, function(x) gam(surface_area~s(percent, k=10), data=x,family=scat))

I am trying to take a list of results that looks like this:

list(structure(list(percent = c(0.950517843, 0.982918911, 0.94428041,

and plug these results into the list of models to get predictions for each Lake_name at each corresponding percent value using lapply like this (the name of my list of results is result):

pred1 <- lapply(model_list, function(x) predict(x, newdata=result, type = "response"))

I am getting an error each time I try to run the predictions off of this list. Error is too long to list completely but it starts with:

Called from: (function (..., row.names = NULL, check.rows = FALSE, check.names = TRUE, 
    fix.empty.names = TRUE, stringsAsFactors = default.stringsAsFactors()) 
{
    data.row.names <- if (check.rows && is.null(row.names)) 
        function(current, new, i) {
            if (is.character(current)) 
                new <- as.character(new)
            if (is.character(new)) 
                current <- as.character(current)
            if (anyDuplicated(new)) 
                return(current)
            if (is.null(current)) 
                return(new)
            if (all(current == new) || all(current == "")) 
                return(new)
            stop(gettextf("mismatch of row names in arguments of 'data.frame', item %d", 
                i), domain = NA)
        }
    else function(current, new, i) {
        if (is.null(current)) {
            if (anyDuplicated(new)) {
                warning(gettextf("some row.names duplicated: %s --> row.names NOT used", 
                  paste(which(duplicated(new)), collapse = ",")), 
                  domain = NA)
                current
            }
            else new
        }
        else current
    }
    object <- as.list(substitute(list(...)))[-1L]
    mirn <- missing(row.names)
    mrn <- is.null(row.names)
    x <- list(...)
    n <- length(x)
    if (n < 1L)

How do I set up a list of models for each Lake_name to run predictions based off another corresponding list of results within lapply?

CodePudding user response：

You need an iterator to move through both the models and the new data. Instead of moving through the models, make it an iterator.

pred1 <- lapply(1:length(model_list), 
                function(x) predict(model_list[[x]], 
                                    newdata = result[[x]], 
                                    type = "response"))
