r - How to convert the values in a dataframe to a dummy values by levels() function? -

-



the given data 

snp1 <- c("aa","gg","ag") snp2 <- c("aa","cc","ac") snp3 <- c("gg","aa","ag") df<- data.frame(snp1, snp2, snp3) colnames(df)<- c('rs10000438', 'rs10000500','rs1000055')

i define data function dominant_dummy. when run codes found goes wrong.

error in if (!check) { : argument of length 0

when debug found argument x in dataframe, , need use function levels(x) check level of x, , assign levels(x)<- c(0,1,1), levels function return null. my purpose convert values in dataframe df dummy values based on conditions.

  snp_lib<- ncbi_snp_query(names(x))   ncbi_snp_query(names(x))   snp_min<- snp_lib$minor   snp_name<- snp_lib$query   snp_min ="a"   snps <- x    check<-substr(levels(snps)[2],1,1)==snp_min

i need assign dummy values dataframe levels(x)<- c(0,1,1). how can that?

library(rsnps) dominant_dummy<- function(x){    snp_lib<- ncbi_snp_query(names(x))   ncbi_snp_query(names(x))    snp_min<- snp_lib$minor   snp_name<- snp_lib$query   snp_min ="a"   snps <- x    check<-substr(levels(snps)[2],1,1)==snp_min   if(!check){     levels(snps)<-c(0,1,1)     snps<-as.numeric(as.character(snp))   }else {levels(snps)<-c(1,1,0)   snps<-as.numeric(as.character(snp))} }  df_3levels<-sapply(1:ncol(df), function(i) dominant_dummy(df[,i, drop=false]))

you can not check levels on data frame. use levels(snps[[1]]) instead check levels on first column. there other errors well.

i have many .npy (numpy) , .json files saved in s3, need download , load these files. for json files downloading files , loading dictionary using following code: obj = s3.object(bucket, key) response = obj.get() body = response['body'].read().decode('utf-8') data = json.loads(body) that way avoid writing .json file disk , reading it. now want same .npy files, equivalent? currently downloading file, saving temp file on disk , loading np.load avoid if possible. following https://stackoverflow.com/a/28196540/3509999 : obj = s3.object(bucket, key) io.bytesio(obj.get()["body"].read()) f: # rewind file f.seek(0) arr = np.load(f) wiki
