[R] Finding and changing .Rprofile
I would like to change my .Rprofile file, but I cannot find it. I use a Mac Pro and RStudio. I believe the file is a hidden file and I have checked for it accordingly. I can not find it with a Spotlight search. It is not in my "default working directory". Is that the same thing as my "home directory"? I believe I can put a new .Rprofile file in any project directory, but that is not what I want to do. I want a .Rprofile file that will apply automatically whenever I start working on another project. Was one installed automatically when I installed R and RStudio many months ago and if so, where can I find it? If it was not installed automatically and I have to create my own, where should I put it? __ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.

Hi, As an FYI, there is a dedicated R list for macOS users: https://stat.ethz.ch/mailman/listinfo/r-sig-mac which should be used for macOS specific questions vis-a-vis R. The default .Rprofile is stored in your user home folder, which is /Users/YourUserName/.Rprofile or abbreviated as ~/.Rprofile. As you note, because it is a hidden file, with a leading '.', Finder and Spotlight will not show it by default. You can change that behavior relative to hidden files, by opening a Terminal and using the following command: defaults write com.apple.finder AppleShowAllFiles TRUE then restart Finder, by using Alt-RightClick on the Finder icon in the dock and selecting Relaunch. You can reverse that behavior by changing the TRUE to FALSE in the above command. If you don't want to make that global change, you can use the following command in a Terminal session: open -a Textedit ~/.Rprofile That will bring up the Textedit editor application with the file loaded. You can then edit the file content and save it. Whichever way you edit the file, be sure to restart any R sessions you have running, so that future R sessions will pick up the changes. Making the change to that file will generally affect all R sessions for your user profile. I don't use RStudio, so it may have other relevant features, and they have their own support lists linked on their site.

[R] as.Date() function
I am having trouble with what must be a very simple problem. Here is a
reproducible example:
library(lubridate)
st <- c("1961-01","1961-04","1983-02")
print(st)
#[1] "1961-01" "1961-04" "1983-02"
st1 <- as.Date(st, format=("%Y-%m"))
print(st1)
#[1] NA NA NA
Why the heck am I getting three NAs instead of three Dates?I have
studied the R documentation for as.Date() and it has not turned on the
light bulb for me.

Re: [R] as.Date() function
Thanks Erin and Jim. You have indeed solved my problem.

Hi Philip:
Here is something to consider:
#potential solution:
sta <- paste(st,"-01",sep="")
st1 <- as.Date(sta, format=("%Y-%m-%d"))
print(st1)
[1] "1961-01-01" "1961-04-01" "1983-02-01"
Hope this helps!

[R] Multi-word column names in a data frame
I am having trouble working with column names in a data frame. My
column names are multi-word text strings and I like it that way. I
want to loop through the columns, plotting graphs for each one, and I
want to use the column names in the chart labels and in the file names
when I save the charts. Here is a simple reproducible example that
does not work.
library(dplyr)
`RefDate` <- as.Date(c("2010-11-1","2010-12-01","2011-01-01"))
`Number of vegetables` <- c(14,23,45)
`Number of people` <- c(20,30,40)
MyData <- data.frame(RefDate,`Number of vegetables`,`Number of
people`,check.names=FALSE)
MyVars <- c("Number of vegetables","Number of people")
for (A in MyVars) {
g2 <- ggplot(MyData,aes(RefDate,eval(parse(text=A + geom_line() +
labs(title = paste(A," adjusted",sep=""))
g2
ggsave(paste(A,".jpg",sep=""),g2,height=5,width=8,dpi=300)
}
