篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了更新R和tidyverse后出现错误相关的知识,希望对你有一定的参考价值。
我一直在使用多个循环来研究拒绝采样代码。更新R和tidyverse
之后,我发现该代码不再起作用,并显示以下错误:
Error: Assigned data `mapply(...)` must be compatible with existing data.
i Error occurred for column `sampled`.
x Can't convert from <integer> to <logical> due to loss of precision.
* Locations: 1.
Run `rlang::last_error()` to see where the error occurred.
In addition: Warning message:
In seq.default(x, y, na.rm = TRUE) :
extra argument ‘na.rm’ will be disregarded
该代码先前有效,并且与先前的问题相关,链接为here。我已尝试通过使用较旧的R(3.6)和tidyverse
(1.3.0)解决(避免)该问题,但是现在我需要使用一些与R的较早版本不兼容的其他程序包我不打算重新编写整个代码,我希望它只需要进行一些调整就可以与较新版本的R和tidyverse
一起使用。
这里是修改后的代码示例,显示的错误与我的实际代码相同:
df <- dfsource temp_df<-df #temp_pithouse_join used for dynamically created samples temp_df$sampled <- NA #blanking out the sample column so I can check against NA for the dynamic detereminatination. temp_df %>% mutate_if(is.factor, as.character) -> temp_df #change factors to characters for (i in 1:100){ #determines how many iterations to run row_list<-as.list(1:nrow(temp_df)) q<-0 while(length(row_list)!=0 & q<10){ q<-q+1 #to make sure that we don't spinning off in an infinite loop for(j in row_list){ #this loop replaces the check values skip_flag<-FALSE #initialize skip flag used to check the replacement sampling for(k in 4:5){ #checking the topoafter columns if(is.na(temp_df[j,k])){ # print("NA break") # print(i) break } else if(is.na(as.integer(temp_df[j,k]))==FALSE) { #if it's already an integer, well, a character vector containing an integer, we already did this, next # print("integer next") next # print("integer next") } else if(temp_df[j,k]==""){ #check for blank values # print("empty string next") temp_df[j,k]<-NA #if blank value found, replace with NA # print("fixed blank to NA") next } else if(is.na(filter(temp_df,ID==as.character(temp_df[j,k]))["sampled"])) { #if the replacement has not yet been generated, move on, but set flag to jump this to the end skip_flag<-TRUE # print("skip flag set") } else { temp_df[j,k]<-as.integer(filter(temp_df,ID==temp_df[j,k])[6]) #replacing IDs with the sampled dates of those IDs # print("successful check value grab") } #if-else } #k for loop if(skip_flag==FALSE){ row_list<-row_list[row_list!=j] } else { next } #sampling section if(skip_flag==FALSE){ temp_df[j,6]<-mapply(function(x, y) if(any(is.na(x) || is.na(y))) NA else sample(seq(x, y, na.rm = TRUE), 1), temp_df[j,"Start"], temp_df[j,"End"]) temp_df[j,7]<-i #identifying the run number if(any(as.numeric(temp_df[j,4:5])>as.numeric(temp_df[j,6]),na.rm=TRUE)){ # print(j) while(any(as.numeric(temp_df[j,4:5])>as.numeric(temp_df[j,6]),na.rm=TRUE)){ temp_df[j,6]<-mapply(function(x, y) if(any(is.na(x) || is.na(y))) NA else sample(seq(x, y, na.rm = TRUE), 1), temp_df[j,"Start"], temp_df[j,"End"]) } #while temp_df[j,7]=i }#if } } #j for loop } #while loop wrapper around j loop if(i==1){ df2<-temp_df }else{ df2<-rbind(df2,temp_df) }#else #blank out temp_df to prepare for another run temp_df<-df temp_df$sampled <- NA temp_df %>% mutate_if(is.factor, as.character) -> temp_df }#i for loop
这是要使用的示例数据,我将其读取为
dfsource
:

答案
[考虑到您遇到的第一个问题(Sample using start and end values within a loop in R),如果您已经逐行循环,我不确定为什么需要mapply
。为什么不只是本例中的内容:
