You should be looking for foreign::data.restore, not data.dump nor read.S. In any case, I think that foreign::data.restore does not recognize S-version4 data.dump files, ones whose first line is ## Dump S Version 4 Dump ## Here is a quickly written and barely tested function that should read data.frames and other simple S+ objects in SV4 data.dump files. It stores the objects it reads from the file 'file' in the environment 'env'. data.restore4 <- function(file, print = FALSE, verbose = FALSE, env .GlobalEnv) { if (!inherits(file, "connection")) { file <- file(file, "r") on.exit(close(file)) } lineNo <- 0 nextLine <- function(n = 1) { lineNo <<- lineNo + n readLines(file, n = n) } Message <- function(...) { if (verbose) { message(simpleMessage(paste("(line ", lineNo, ") ", paste(..., collapse = " "), sep = ""), sys.call(-1))) } } Stop <- function(...) { stop(simpleError(paste(paste(..., collapse = " "), sep = "", " (file ", deparse(summary(file)$description), ", line ", lineNo, ")"), sys.call(-1))) } txt <- nextLine() stopifnot(txt == "## Dump S Version 4 Dump ##") .data.restore4 <- function() { class <- nextLine() mode <- nextLine() length <- as.numeric(tmp <- nextLine()) if (is.na(length) || length%%1 != 0 || length < 0) { Stop("Expected nonnegative integer 'length' at line ", lineNo, " but got ", deparse(tmp)) } if (mode == "character") { nextLine(length) } else if (mode == "logical") { txt <- nextLine(length) lglVector <- rep(NA, length) lglVector[txt != "N"] <- as.logical(as.integer(txt[txt != "N"])) lglVector } else if (mode %in% c("integer", "single", "numeric")) { txt <- nextLine(length) txt[txt == "M"] <- "NaN" txt[txt == "I"] <- "Inf" txt[txt == "J"] <- "-Inf" atomicVector <- rep(as(NA, mode), length) atomicVector[txt != "N"] <- as(txt[txt != "N"], mode) atomicVector } else if (mode == "complex") { txt <- nextLine(length) txt <- gsub("M", "NaN", txt) txt <- gsub("\\<I\\>", "Inf", txt) txt <- gsub("\\<J\\>", "-Inf", txt) atomicVector <- rep(as(NA, mode), length) atomicVector[txt != "N"] <- as(txt[txt != "N"], mode) atomicVector } else if (mode == "list") { vectors <- lapply(seq_len(length), function(i).data.restore4()) vectors } else if (mode == "NULL") { NULL } else if (mode == "structure") { vectors <- lapply(seq_len(length), function(i).data.restore4()) if (class == ".named_I" || class == "named") { if (length != 2) { Stop("expected length of '.named_I' component is 2, but got ", length) } else if (length(vectors[[1]]) != length(vectors[[2]])) { Stop("expected lengths of '.named_I' components to be the same, but got ", length(vectors[[1]]), " and ", length(vectors[[2]])) } else if (!is.character(vectors[[2]])) { Stop("expected second component of '.named_I' to be character, but got ", deparse(mode(vectors[[2]]))) } names(vectors[[1]]) <- vectors[[2]] if (identical(vectors[[2]][1], ".Data")) { # a hack - really want to know if vectors[[1] had mode "structure" or not do.call(structure, vectors[[1]], quote = TRUE) } else { vectors[[1]] } } else { vectors # TODO: is this ok?
