Actually, I'm having trouble with importing a CSV file in my script in Rstudio. I am trying:
d <- read.table(file="table1.csv",sep="\t",header=T)
but it says that there is an error in file and "rt".
Type 'getwd()' in the console. If what returns isn't the same path as the file you're trying to read in, change this with setwd("[your filepath here]"). If you want a graphical solution instead, you can use the Set As / Go To Working Directory commands under the 'More' menu in RStudio's Files viewer (bottom right window).
Then try d <- read.csv("table1.csv")

Bit of a newbie for R, R Studio and Markdown but I am trying to use the render() function on my Rmd file and I get the following error:
Error: could not find function "render"
If I try to use the following I get this error:
markdown::render("MarkdownExample.Rmd")
Error: 'render' is not an exported object from 'namespace:markdown'
Still yesterday I could use the render fonction without any problem. Would anyone know what to do?
Thanks in advance
Shouldn't it be rmarkdown::render?

I am new to R and now I have an issue while I try to read CSV files in a loop. My CSV files are named as
result_file_1.csv , result_file_2.csv,....result_file_10.csv
So I planned to read a CSV by the below code:
for(i in 1:10){
t1=read.csv("result_file_i.csv")
// rest of my code
}
I also tried:
for(i in 1:10){
t1=read.csv("result_file_"+i+".csv")
// rest of my code
}
both did not work. Any help is appreciated
As suggested above I used paste0("result_file",i,".csv") and it worked fine.

I'm working on Slackware and I'm trying to change my working directory in order to import a xlsx.
setwd("</home/diego/Downloads>")
Error in setwd("</home/diego/Downloads>") :
cannot change working directory
This happens when directory path is wrong. Two steps may solve this:
First, check what's your current working directory in terminal or use getwd() with R
Second, setwd("path") according to your current working directory, for example, setwd("diego/downloads"), setwd("../../abc/def"), certainly you should drop the < and >
Drop the < and > from the directory name.

Looking to read in an .xlsx file. This is an assignment so I specifically can't use Excel first to convert it to .csv.
Tried using read.xlsx which couldn't be found so I tried 'library(xlsx)' which was not a package according to R.
Does anyone know if there's something glaringly obvious that I'm not doing? Is the package called something different? Is there a different/better way to read an xlsx file?
Thanks!

I am having the problem that when I use setwd() with a path that includes spaces (e.g. setwd("C:/Users/Name/My Documents/") I get the error message
"cannot change working directory"
I am a bit suprised that I did not find much about this here or on google - so it must either be a rare error or everyone knows about it I reckon. Either way, is there a why to work around it?
I am using Windows 7 and R version 3.0.2.
R cannot setwd into a directory that it doesn't have 'x' (execute) permission for.
This should work, but if really needed, you can use the function shortPathName.
> shortPathName("C:/Program Files (x86)/Adobe/")
[1] "C:\\PROGRA~2\\Adobe\\"
I can replicate your error if I just copy and paste
setwd("C:/Users/Name/My Documents/")
to console as is. The problem is that R cannot find the specified path. I believe that you should replace "Name" with your username...
If I replace "Name" with my username, it works as expected.
