Identified as root cause of a bug in data.table: https://github.com/Rdatatable/data.table/issues/3267 On my machine, strtoi("", base = 2L) produces NA_integer_ (which seems consistent with ?strtoi: "Values which cannot be interpreted as integers or would overflow are returned as NA_integer_"). But on all the other machines I've seen, 0L is returned. This seems to be consistent with the output of...

Thanks very much for your answer. I?m trying the function ?strtoi? but it fails to convert character to numeric after the command "set[index] <- strtoi(set[index])". > strtoi(set[index]) ## This works: all values are numeric !!!

Hi, I've used the following patch First because re-defining strtoi is a problem, and it's named Strtoi elsewhere. Second because that is the sole use of strtoi that isn't Strtoi. Third, use = instead of ==, which is bash-specific. Additionally I must note there are a number of tests in configure.ac which do not append x to the beginning of the string. I h...

I am new to R. I thing this will be simple, but I don't yet know my way around. I am generating character strings from the system clock that represent integers, and I want to convert them to integer values. Strtoi works well, except when there are leading zeros on the string. Could anyone suggest a way to remove those leading zeros? Thanks Paul -- E.

hi everyone . Here I have a text where there are some integer and string variables.But I can not read them by readLines and scan the text is : weight ;30;130 food:2;1;12 color:white;black the first column is the names of the variables and others are the value of them. the column in different line are different. Can anyone help me ? -- TANG Jie Email: totangjie@gmail.com Tel: 0086-2154896104

My attempts with rawToChar and strtoi seems to take drastically longer for reasonably lengthy bytepos, presumeably because of string manipulations/storage, but possibly I am doing it wrong somehow. If there is no better way in R, would there be much value in implementing this in C, for example, or would the computational improvement be...

Hi, How would you calculate the "mean colour" of several colours, for example c("#FF7C00","#00BF40","#FFFF00")? Yours, Atte Tenkanen

Hi, Is it possible to convert a string vector to integer or numeric vector? In my situation I receive data in a string vector and have to convert it based on a given type. -- Rajesh.J [[alternative HTML version deleted]]

I want to put the "plus or minus" symbol into a character variable, so that this can be turned into a factor and be displayed in the "strip" of a faceted ggplot2 plot. A very nice solution, thanks to Professor Ripley's post of Nov 16, 2008; 3:13pm, visible at http://r.789695.n4.nabble.com/Symbols-to-use-in-text-td874239.html and subsequently
