> # make value 1 and NA 0 > colpos[!is.na(colpos)] <- 1.0 > colpos[is.na(colpos)] <- 0.0 > > # sum number of values on a given day > rowsum(colpos, ) Do you want by chance to get how many nonnumeric values are in each row of your data frame in station columns? I...
The post Replace NA with Zero in R appeared first on Data Science Tutorials Replace NA with Zero in R, Using the dplyr package in R, you can use the following syntax to replace all NA values with zero in a data frame. Substitute zero for any NA values. C
This casual note is to record how to use R to replace the NA with 0 or any string. Generally, NA can be generated for different reasons, like unclean data, data transformation, or missing values. Otherwise, we have to convert NA to zero or other stings in order to present them in tab...
replace_na() 返回与 data 类型相同的对象。 也可以看看 dplyr::na_if() 将指定值替换为 NA; dplyr::coalesce() 用其他向量的值替换 NA。 例子 # Replace NAs in a data frame df <- tibble(x = c(1, 2, NA), y = c("a", NA, "b")) df %>% replace_na(list(x = 0, y = "unknow...
na_matrix<-is.na(df) 1. 3. 去除NA值 然后,我们可以使用na.omit()函数去除DataFrame中的NA值,得到一个新的DataFrame"clean_df": clean_df<-na.omit(df) 1. 4. 替换NA值 如果我们不想删除包含NA值的行,而是将NA值替换为指定的值,可以使用na.replace()函数。假设我们将NA值替换为0,可以使用以下代码...
## CDC27_mut 0 0 0 NA ## CDC73_mut 0 0 0 NA ## CDH1_mut 0 0 0 NA ## CDK12_mut 0 0 0 NA # replace all non-finite values with 0 markerMat[!is.finite(markerMat)] <- 0 colnames(markerMat)<-cols dim(markerMat) #1315 1389 ...
Based on is.na, it is possible to replace NAs with other values such as zero…is.na_replace_0 <- data$x_num # Duplicate first column is.na_replace_0[is.na(is.na_replace_0)] <- 0 # Replace by 0…or the mean.is.na_replace_mean <- data$x_num # Duplicate first column x_...
4. 替换 NA (1) replace_na() 实现用某个值替换一列中的所有 NA 值,该函数接受一个命名列表,其成分为列名= 替换值: starwars %>% replace_na(list(hair_color = "UNKNOWN", height = mean(.$height, na.rm = TRUE)))(2) fill()
Replace 0 with NA in R replace Function in R The R Programming Language In this R tutorial you learned how toreplace certain data frame values. Please let me know in the comments section, if you have any additional questions. Furthermore, don’t forget to subscribe to my email newsletter ...
您可以使用na_if()将"aa"替换为NA，并使用replace_na()将NA替换为"missing"。Base
