Hi Everyone, I am very new to R. When i run the code yesterday, it was working fine. I was able to find gene annotation.
somehow, today, when i try to run it again, it is giving me errors message that i don't understand. It says that it cannot open file. what file is it looking for? ###################################################### ##make sure to install and load annotationtool in R annotation_HGU133Plus2 <- read.csv("c://affymetrix.csv", colClasses = "character") annotation_probesets <- scan('c://ttest.csv',skip=1,what='') dataDirectory <- system.file("data", package = "annotationTools") annotation_stuff <- read.csv(paste(dataDirectory, annotation_HGU133Plus2, sep = "/"), colClasses = "character") myPS <- c(annotation_probesets) getGENESYMBOL(myPS, annotation_stuff) getGENEONTOLOGY(myPS, annotation_HGU133Plus2) ###############error message######################## > annotation_stuff <- read.csv(paste(dataDirectory, + annotation_HGU133Plus2, sep = "/"), colClasses = "character") Error in file(file, "r") : unable to open connection In addition: Warning messages: 1: In file(file, "r") : only first element of 'description' argument used 2: In file(file, "r") : cannot open file 'C:/PROGRA~1/R/R-26~1.2/library/annotationTools/data/c("1007_s_at", "1053_at", "117_at", "121_at", "1255_g_at", "1294_at", "1316_at", "1320_at", "1405_i_at", "1431_at", "1438_at", "1487_at", "1494_f_at", "1552256_a_at", "1552257_a_at", "1552258_at", "1552261_at", "1552263_at", "1552264_a_at", "1552266_at", "1552269_at", "1552271_at", "1552272_a_at", "1552274_at", "1552275_s_at", "1552276_a_at", "1552277_a_at", "1552278_a_at", "1552279_a_at", "1552280_at", "1552281_at", "1552283_s_at", "1552286_at", "1552287_s_at", "1552288_at", "1552289_a_at", "1552291_at", ', reason 'No such file or directory' > thank you, claire -- View this message in context: http://www.nabble.com/Errors-in-in-my-code-tp15910042p15910042.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list 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.
