Hello, how do you create a histogram with a data frame? year snow.cover 1970 6.5 1971 12.0 1972 14.9 1973 10.0 1974 10.7 1975 7.9 ... mydata=data.frame(year=c(1970,...),snow.cover...
Hello, does anyone know when the R 3.3 binary for RH Linux 7 will be available from the RedHat Repository? One of my R scripts, which uses ggplot2, works fine in RStudio 3.24 on Windows, but doesn't...
Hello, I would like to generate a small map (say 10cm x 10cm) of France showing cumulative numbers by Distribution Center stored in a database: DISTRIBUTION_CENTER COUNT Paris 122 Paris 3 Paris 21 Lyon 12 Lyon 4444 Lyon 33...
Hello, I have written an R script which displays a bar chart using the ggplot2 library (please refer to code excerpt at the bottom of this e-mail). Although the bar chart is displayed OK in the Windows version of...
Hello, 1) What is the difference between a "data frame" (J H Maindonald, Using R, p. 12) and a "vector"? In Using R, the author asks the reader to enter the following data in a data frame, which I will...
Hello, the following function, which stores numeric values extracted from a binary file, into an R matrix, is very slow, especially when the said file is several MB in size. Should I rewrite the function in inline C or in...

Please find below code that attempts to read ints, longs and floats from a binary file (which is a simplification of my original program). Please disregard the R inefficiencies, such as using rbind, for now. I?ve also included Java...
The only difference between the below code and my program is that the former assumes that the file only contains one row of 10 ints + 10 floats , whereas my program doesn?t know in advance how many rows the file...
Hi Jim, this is exactly the answer I was look for. Many thanks. I didn?t R had a pack function, as in PERL. To answer your earlier question, I am trying to update legacy code to read a binary...
