r - Getting specific line from Cash Flow -

i'm trying data cash flow getfinancials function in r.

library(quantmod) s <- c("aapl","goog","ibm","gs","amzn","ge") fin <- lapply(s, getfinancials, auto.assign=false) names(fin) <- s 

but when try specific line with

fin$aapl$cf$a["cash operating activities"] fin$aapl$cf$a["capital expenditures"] 

i na return. how can these specific lines cash flow?

since fin$aapl$cf$a matrix, need comma after name because asking row name. without comma asking vector element named "cash operating activities", , since have matrix individual elements not named.

class(fin$aapl$cf$a) # [1] "matrix" "cash operating activities" %in% rownames(fin$aapl$cf$a) # [1] true  ## no comma - na because "cash operating activities" not named vector element fin$aapl$cf$a["cash operating activities"] # [1] na 

this can more illustrated with

x <- 1 x["x"] # [1] na 

since x has no named element "x", na. want following.

## comma - asking row "cash operating activities" fin$aapl$cf$a["cash operating activities", ] # 2014-09-27 2013-09-28 2012-09-29 2011-09-24  #      59713      53666      50856      37529  

since these matrices, rows requested on left side of comma, columns on right, , single named elements no comma.
