[Rcicr-users] CI Errors

[Dotsch, R. (Ron)]

Hi Dan,

Thank you for sending your files. I made some corrections to your script, below:


baseimage <- 'AndN'
rdata <- 'rcicr.Rdata'
responsedata <- read.csv('rcicrdata.csv')

ci <- generateCI2IFC(responsedata$Face_All, responsedata$correct, baseimage, rdata)
cis <- batchGenerateCI2IFC(responsedata, 'subject_nr', 'Face_All', 'correct', baseimage, rdata)
cis <- batchGenerateCI2IFC(responsedata, 'Emotion', 'Face_All', 'correct', baseimage, rdata)


The rdata filename did not correspond to the name of the rdata file that you sent me, but this might be unrelated to your issues if you renamed it before sending to me. Besides that, the generateCI2IFC function takes as first parameters the actual column vectors of the data frame, not the column names. I could not find an error in the first batchGenerateCI2IFC and it runs fine for me. In the second call, ‘Emotion’ had to be the second parameter, not the fourth.

Hope this works.

Best,

Ron

Dear Dan,

Here too, I still need to work on more user friendly error messages. Based on your description, it seems like rcicr can’t find the .Rdata file. Is this file in your current working directory? And are you sure the label you used for base image is correct (case sensitive)?

For the last command the problem is that the parameters ‘Emotion’ should precede ‘Face_All’, assuming that Emotion is the column by which you wat to split the data.

If that’s not the problem, could you send me the .Rdata file and your .csv file to debug? Please do so off list.

Best,

Ron

Hello all,

I apologize for not being too proficient in this package, but I am running into some additional errors while trying to compute classification images. I’ve reproduced the script and errors below. I’ve tried every iteration for producing CIs, but get an error for every one (errors bolded). Any help in figuring out how to remedy this issue would be greatly appreciated.

> library(rcicr)
> baseimage <- ‘AndN’ #What I named the image when producing the stim
> rdata <- 'rcicrRC2.Rdata’ #Name of my data file computed while making the images
> responsedata <- read.csv('rcicrdata.csv’)

> ci <- generateCI2IFC(responsedata, 'Face_All', 'correct', baseimage, rdata)
   Error in readChar(con, 5L, useBytes = TRUE) : cannot open the connection
   In addition: Warning message:
   In readChar(con, 5L, useBytes = TRUE) :
   cannot open compressed file 'AndN', probable reason 'No such file or directory’

> cis <- batchGenerateCI2IFC(responsedata, 'subject_nr', 'Face_All', 'correct', baseimage, rdata)
   Error in matlab::zeros(length(names(cis)), 2) :
  dimensions must be a positive quantity

> cis <- batchGenerateCI2IFC(responsedata, 'Face_All', 'correct','Emotion', baseimage, rdata)
   Error in stimuli_params[[baseimage]][stimuli, ] :
   only 0's may be mixed with negative subscripts

Best,
Dan
